Remarks: |
The variability of IW Aur was discovered by Hoffmeister (1964).
The variable was classified in the GCVS as a semiregular pulsating star (SR) without
light elements.
According to ROTSE1 data (Wozniak et al., 2004), it is a new classical Cepheid. M-m
= 0.33P.
Apparently NSVS 6974851 is a blended image of two or even three stars (IW Aur, GSC
2407-00366 and GSC 2407-01936). Thus, the magnitudes in maximum and minimum are not
confined
to
IW Aur, and the amplitude of variability is underestimated. |
