I present a catalog of newly detected Multi-Mode
Radially Pulsating (MMRP) variable stars that pulsate in the
fundamental, first, second, or third-overtone modes. This catalog
includes 50 double- and multi-mode stars. Among variability types
of these stars, we find classical Cepheids, RR Lyrae, and
high-amplitude Scuti (HADS) variables. Additionally, I
studied 14 known multi-periodic variables.
I analyzed all observations available for these stars in the ASAS-SN and ZTF online public archives using the period-search software developed by Dr. V.P. Goranskij for Windows environment. Light elements and parameters of oscillations were determined. |
In the course of my search for double-mode and multiperiodic variable stars using available photometric archives, I detected 50 new Multi-Mode Radially Pulsating (MMRP) variables. These stars pulsate in the fundamental, first-overtone, second-overtone, or third-overtone modes. This article continued the series of my previous papers (Khruslov. 2018a, 2021a, 2022, etc.). Among variability types of these stars, we find classical Cepheids, RR Lyrae stars, and high-amplitude Scuti variables.
Additionally, I studied 14 known multi-periodic variables (see additional Tables with index 'a') as a part of the program of preparation for their inclusion in the General Catalog of Variable Stars, GCVS (Samus et al., 2017).
Searching for double periodicity, I mainly used data available in the photometric archive of the All-Sky Automated Survey for Supernovae (ASAS-SN, Shappee et al., 2014; Kochanek et al., 2017) and the Zwicky Transient Facility (ZTF, Bellm et al., 2019; Masci et al., 2019)
The method I use to search for multiperiodicity is similar to that described in my earlier paper (Khruslov, 2021). To search for candidate multi-mode variables, I used AAVSO VSX1database, the ASAS-SN catalogs of variable stars2 database (Jayasinghe et al., 2018, 2019a, 2019b, 2020, 2021), ZTF catalog of periodic variable stars3, Chen et al. (2020).
The radial pulsation modes were identified by their period ratio ( ); see the study on this problem by Petersen (1973), Petersen & Christensen-Dalsgaard (1996), Smolec & Moskalik (2010), and others.
For this study, I used the data of the ASAS-SN4 database and the ZTF data available through the SNAD ZTF viewer5, Malanchev et al. (2021). The light elements are based on data from these two surveys, individual cases are described in Comments. The magnitude ranges and amplitudes in the tables are given according to this data. I used and bands of ASAS-SN, and and bands of ZTF.
Additionally, in individual cases, I analyzed available data from other archives: the Wide Angle Search for Planets (SuperWASP6, Butters et al., 2010; 8 variables), the Catalina Sky Surveys (CSS7, Drake et al., 2009; 5 variable), the All Sky Automated Survey (ASAS-38, Pojmanski 2002; 2 variables).
The ASAS-3 data used in this paper were downloaded before April 2022, in accordance to requirements of authors of this survey for users located in Russia.
The SuperWASP observations are available as FITS tables, which were converted into ASCII tables using the OMC2ASCII9program, as described by Sokolovsky (2007).
The survey data used in this study for the program stars are available online in the html version of this paper as a zip archive. This file also includes all light curves of the variables and cross-identification tables for all stars.
In individual cases, the ZTF data contained continuous data series with duration of a whole night of observations. This created some difficulties in the analysis of data. To eliminate these problems, we used averaged values (the mean for about 10 neighboring points) for our analysis. These averaged values are presented in the data files below the main data series. The rows of these supplements contain mean HJD times, mean magnitudes, and number of averaged points.
In this paper, the following identification names are used for variables.
For new multi-periodic stars, with multi-periodicity first detected in this study, I use designations of the form MMRP-XXX (where MMRP is the name of the present program, aimed at discoveries of Multi-Mode Radially Pulsating variables, and XXX is the sequence number in the catalog). An example: MMRP-010.
For the known multi-periodic stars, for which this paper presents new light elements, I used designations in the form MMRP_JXXXXXX.XX+XXXXXX.X (the abbreviation MMRP followed with equatorial coordinates for the equinox 2000.0). An example: MMRP_J054223.13+275647.6.
In the present paper, I use an original notation for types of multiperiodic variables. The basics of the classification were presented by N.N. Samus and the GCVS team at the XXVI IAU General Assembly in Prague, 200610: classical GCVS types of radial pulsating variables were appended with numbers of pulsation modes (0 - fundamental mode, 1 - first overtone, 2 - second overtone). Double-mode variables are marked with a set of detected modes. For example, RR Lyrae stars can be designated as RR0, RR1, and RRB01 (in the old system, RRAB, RRC, and RR(B), respectively, B meaning "beat"). A similar notation was proposed for classical Cepheids (DCep0, DCep1, DCepB01, and DCepB12).
In the new MMRP classification, the numerical identification of pulsation modes is preserved, and the variability type is designated with a single letter. Additional characteristics are introduced with an additional index. An arrow indicates the cases of mode switching.
I. Types of variable stars:
C - classical Cepheids;
W - W Virginis, or type II Cepheids;
R - RR Lyrae stars;
D - Scuti stars.
II. Numbers of pulsation modes:
0 - fundamental mode;
1 - first overtone;
2 - second overtone;
3 - third overtone.
III. Addition designations:
n - additional non-radial mode;
m - amplitude modulation;
- mode switching.
Examples of designations of multi-periodic variables: C01, C12, C12m, D01, D123, D23, D12n, D0123, R01, W01, C12C1, R01R0, R1R01.
The classical GCVS designations of mono-periodic variability types can be converted as follows: DCEP = C0, DCEPS = C1, RRAB = R0, RRC = R1; for multi-mode variable types, RR(b) type can be written as R01 (there are no R12 stars confirmed with certainty); CEP(B) is a group of types designated as C01, C12, C012, C123, and W01; DSCT(B) and SXPHE(B) is a group of all multi-mode D types.
The types from the VSX database are converted as follows: RRd = R01; DCEP(B) = C01; DCEPS(B) = C12; CWB(B) = W01; HADS(B) is a group of all multi-mode D types.
Double-mode type II Cepheids (W Virginis type) and mode-switching stars are not included in this catalog. An example of a W01 star, USNO-B1.0 0992-0344981, can be found in Khruslov (2021). An example of an R01R0 star is USNO-B1.0 1171-0309158, see Khruslov et al. (2017). Other stars of these types may be included in later issues of MMPR catalogs.
in addition to type C12, I used type C*12 that includes stars morphologically close to type C12 but with shorter periods characteristic of R1 stars (see Subsection 6.3).
Besides the basic classification, I used two other indices: n for cases of detected additional non-radial modes; m for detected amplitude modulation with slow variation from one season to another.
For a correct presentation of information on multi-periodic variables in the MMRP catalog Tables, I use a multi-row format, with data presented in several sub-rows, each of them corresponding to an individual detected radial pulsation mode. Modes of pulsations are arranged in order of increasing pulsation frequency: the top sub-row is fundamental mode, the first overtone is below it, still lower are the second overtone, third overtone, and so on.
Each multi-row of the main Table (see Tables 1 and 1a) contains general information on the star: number in the Catalog of Multi-Mode Radially Pulsating (MMRS) stars; equatorial coordinates J2000 (for the earlier known MMRP stars, the coordinates are a part of the name); magnitude range (magnitudes at maximum and at minimum); type of multi-periodicity; and then, information about individual modes is presented in sub-rows (light elements, period and epoch of maximum; semi-amplitude; asymmetry parameter of the phased light curve, M-m). The period ratio (shorter period / longer period) is given for each pair of adjacent sub-rows (in the sub-row for the longer period).
The equatorial coordinates are given according to the Gaia EDR3 catalog. The tabulated magnitude range is for the photometric band indicated in brackets ( and are ASAS-SN and magnitudes; and are ZTF and magnitudes). The data in these two columns are in two adjacent sub-rows. Coordinates: top - Right Ascension, bottom - Declination; magnitude range: top - maximum, bottom - minimum.
Individual mode characteristics: period is expressed in days; epoch is in one of the following formats: or ; semi-amplitude in the photometric band indicated in the "Magn." column; the M-m parameter is expressed in fractions of the period.
Tables 2 and 2a contain references to comments that supplement the data in the main table, and also provide information about the history of the variability studies for individual stars. The numbers correspond to the list below the tables.
Tables that supplement the main Table (Table 1 with Comments) follow, they contain general information on the stars. Tables 3 and 3a contain semi-amplitudes and magnitude ranges in all bands used in the ASAS-SN and ZTF surveys: , , , and . The data in "Magnitude range" columns is separated between two adjacent sub-rows: top - maximum, bottom - minimum. These tables contains amplitudes for four bands, so they partially duplicate Tables 1 and 1a. Tables 4 and 4a contain the known information according to catalogs and photometric surveys: color indices (2MASS), and (APASS), (ASAS-SN), and (ZTF); and Galactic latitude (in degrees). These data are used for classification of variables.

An example of light curves for one of the stars, MMRP-049, is displayed in Fig. 1. Top panels present data folded with the fundamental-mode and first-overtone periods. Bottom panels show the same curves after prewhitening the other oscillation (if , and interaction frequencies or non-radial frequencies were excluded, it is also noted). Along with the light curves, we present power spectra of the double-mode variables, for the raw data and after subtraction of the dominant mode (first-overtone oscillations for MMRP-049). The structure of the power spectra shows that the secondary periods are real.
The light curves from the ASAS-SN surveys are available online in the html version of this paper as a zip archive (see Section 2). The light curves are given in the format displayed in Fig. 1. A similar and more complete format is used for triple- and quadruple-mode variables.
Among the 50 stars with multi-periodicity discovered in this study, there are 15 Classical Cepheids (two stars of the C01 type, 8 stars of the C12 type, and 5 stars of the C*12 type); four RR Lyrae stars of the R01 type; 31 high-amplitude Scuti stars (double-mode: 9 D01 stars, 12 D12 stars, 4 D23 stars; triple-mode: 4 D012 stars and one D123 star; and one quadruple-mode star of the D0123 type).
Among the 14 known multi-periodic stars studied in this paper, there are 5 Classical Cepheids (three of C01 type, one of C12 type, and one of C*12 type); four RR Lyrae stars of R01 type; 5 high-amplitude Scuti stars (3 of D01 type, one of D12 type, one of D012 type).
In this paper, the distribution by variability type is not statistically significant. In fact, in the sample of multi-periodic variable stars, the largest fraction belongs to R01 stars. The number of D01 stars is slightly lower. Next in number are the first- and second-overtone variables of different types (D12 and C12) and C01 Cepheids. For the present paper, I selected the rarest and most interesting objects encountered in my search for multi-periodicity.
The Petersen diagram for all MMRP variables studied in this paper is displayed in Fig. 2.

In the photometric data of recent surveys, we find more and more Scuti stars with light-curve asymmetry opposite compared to brightness variations of typical pulsating stars. Pietrukowicz et al. (2020) show four examples of phased light curves of monoperiodic Scuti variables with inversion of asymmetry (the rising part lasting longer than the fading one), and classify these stars as likely first-overtone pulsators.
In this paper, I present a confirmation of this assumption using multiperiodic stars. I detected 10 double- and multi-mode variables with one of the modes showing asymmetry inversion. Among these stars, three are of the D01 type (MMRP-22, MMRP-49, and MMRP_J171059.14-351034.8), four stars belong to the D12 type (MMRP-19, MMRP-23, MMRP-26, and MMRP-32), two stars are of the D012 type (MMRP-24 and MMRP_J160331.49-494754.4), and one star is of the D0123 type (MMRP-10). In all these cases, the mode with asymmetry inversion is the first overtone.
An example of the light curves of one of the stars with asymmetry inversion (MMRP-49) is shown in Fig. 1.
The maximal asymmetry inversion was detected for MMRP_J171059.14-351034.8, .
All these stars have the longest periods for Scuti stars, (for four monoperiodic cases by Pietrukowicz et al., 2020, the periods are within the renge ).
In addition, a slight inversion of asymmetry was detected for MMRP-011, a star of the C*12 type (). MMRP-011 ( , ) is similar to the D12 star MMRP-032 (, ) and to two known double-mode first- and second-overtone variables with a slight inversion of asymmetry, V798 Cyg ( , ) and V1719 Cyg ( , ). Note both the morphological similarity of the light curves and the stars' similar position relative to the Galactic plane.
In addition to the C12 type, I used the C*12 type that includes stars morphologically close to the C12 type (asymmetry parameter or slightly inverted asymmetry, with a small hump at the beginning of the brightness increase), but with shorter periods ( ) characteristic of R1 stars (RRC), bordering Scuti stars. All these stars are located near the Galactic plane. This classification is based on OGLE13 and Gaia DR3 catalogs (Gaia Collaboration, 2022), which classified similar stars as first- and second-overtone Cepheids. In my study, 6 stars belong to the C*12 type: MMRPB€“005, MMRPB€“011, MMRPB€“027, MMRPB€“040, MMRPB€“042, and MMRP_J054223.13+275647.6 = IY Tau.
It should be noted that in the OGLE classification (see Soszyn'ski et al., 2020), a number of stars from the MMRP list with even shorter periods (of δ Scuti type in my classification) are attributed to first-overtone Cepheids (MMRPB€“002 and MMRPB€“032). Some other variables may also be related to this type of stars (MMRPB€“001 and MMRPB€“010).
For 7 variables, slow amplitude modulation (variations from one season to another) was detected. For these stars, the tabulated variability type included the letter "m" (for example, C12m, D12m, D01m). These are mainly cases of amplitude modulation of the second-overtone mode for the first- and second-overtone double-mode Scuti variables (four D12m type stars: MMRP-001, MMRP-16, MMRP-19, and MMRP-32). One D01m star (MMRP-33) showed amplitude modulation of the first-overtone mode. One triple-mode Scuti star of type D012m (MMRP-24) showed possible amplitude modulation of all its radial pulsation modes. Also, one C*12m Cepheid star, MMRP_J054223.13+275647.6 = IY Tau, showed amplitude modulation of the second-overtone mode.
In some cases, a periodic amplitude variation is possible, but, in a number of cases, it also can be mode switching.
Two examples of amplitude modulation are shown in Figs. 3 and 4. MMRP-033 it a possible mode-switching case. MMRP-032 is possibly a case of periodic amplitude variations (during short time intervals of observations, the star shows the "episodic" multiperiodicity; for intervals and variability amplitudes, see Comments to Table 1).

In my study, 6 triple-mode variables were detected. Five of these stars belong to the D012 type: MMRP-012, MMRP-014, MMRP-024, MMRP-039, and MMRP_J160331.49-494754.4. In the case MMRP_J160331.49-494754.4, the second-overtone mode was not earlier known (in the OGLE database, the star was classified as a variable with two periods, those of the fundamental and first-overtone modes). The sixth star, MMRP-002, belongs to the D123 type.
In all cases of the five D012 stars, with a single exception of MMRP-014, the first-overtone mode dominates. The first-overtone mode also dominates for the D123 star MMRP-002. In two cases, the light curve of the first-overtone oscillation showed asymmetry inversion.
One case, MMRP-010, is a quadruple-mode Scuti star of the D0123 type. Additionally, it is an equidistant quadruplet with the frequency differences . The light curve of the first-overtone oscillation of this star also shows inverted asymmetry.
Netzel et al. (2022) presents 14 quadruple-mode Scuti stars of the D0123 type from the OGLE database (Galactic bulge). Among them, no one is an equidistant quadruplet. These authors also presented the discovery of numerous triple-mode Scuti star of the D013 type (221 variables), their number considerably exceeding that of the D012 stars (145 variables). In my study, no D013 stars were detected.
In this paper, I present my detection of four double-mode Scuti stars pulsating in the second- and third-overtone modes, type D23 (MMRP-020, MMRP-031, MMRP-041, and MMRP-045 = V2702 Cyg). Earlier, I found two stars of this type. The first of them is FH Cir (Khruslov, 2010, first classification as a Scuti star with nonradial pulsations; , ; the star was reclassified as a D23 variable by Khruslov, 2016, PhD dissertation14). The second of them is V3124 Cyg (Khruslov, 2014, , ).
According to my study, the second-overtone periods of D23 stars range from to . The period ratio is from to .
For one of the stars, MMRP-031, I detected an amplitude modulation of the third-overtone mode that can be interpreted as Blazhko effect with the period or as a non-radial mode with a frequency close to that of the third-overtone mode, . This case can be possibly classified as a D23n star, where the letter "m" in the MMRP catalog designates long-term variations and is not used for stars with Blazhko effect.
It is particularly interesting that Netzel et al. (2022) did not detect any stars of the D23 type.
