Majid, R.C. Lamb, D.J. Macomb Comments: 26 pages, 10 figures, submitted to ApJ V rabote soobshaetsya ob otkrytii novogo rentgenovskogo pul'sara s periodom 202 s i podtverzhdaetsya obnaruzhenie nedavno otkrytogo pul'sara s periodom 263 s v Malom Magellanovom Oblake (MMO). Oba istochnika otozhdestvleny s ochen' molodymi B-zvezdami, t.e. vhodyat v massivnye dvoinye sistemy. V nastoyashee vremya v MMO izvestnyi 24 rentgenovskih pul'sara iz kotoryh 14 ostayutsya neotozhdestvlennymi v optike. Eshe odin rezul'tat dannoi raboty - novoe znachenie predpolagaemogo perioda anomal'nogo rentgenovskogo pul'sara AXP CXOU J010043.1-721134 ravnoe 8.0 s (ranee eta zhe nablyudatel'naya gruppa davala znachenie perioda 5.4 c). astro-ph/0312044 Parallaksy pul'sarov po nablyudeniyam VLBA na 5 GGc (Pulsar Parallaxes at 5 GHz with the Very Long Baseline Array) Authors: S.Chatterjee et al. Comments: 8 pages, 3 figures, 3 tables; submitted to ApJ Rasstoyanie do pul'sarov - samaya ser'eznaya problema dannoi oblasti nablyudatel'noi astrofiziki, dlya bol'shinstva iz nih rasstoyanie meryaetsya po mere dispersii i imeet nizkuyu tochnost'. Poetomu izmerenie rasstoyanii do pul'sarov lyubym drugim, osobenno pryamym sposobom, ochen' vazhno i interesno. V dannoi rabote opublikovany izmereniya parallaksov samyh blizkih i samyh yarkih pul'sarov na seti antenn VLBA (Very Long Baseline Array) v SShA na chastote 5 GGc. Parallaksy izmeryalis' dlya pul'sarov B0329+54, B0355+54 i B1929+10, dlya niz bylo provedeno 7 serii nablyudenii, razdelennyh periodom v 2 goda (t.e. ih nablyudeniya dlilis' 12 let). Dlya pul'sara B0329+54 iz-za bol'shih sistematicheskih oshibok poluchena tol'ko verhnyaya ocenka pi<1.5x10-3 ". Dlya dvuh drugih pul'sarov izmereny parallaksy i sobstvennye dvizheniya. Dlya B0355+54 pi=(0.91+/-0.16)x10-3 " (d=1.04+0.21-0.16 KPK), a poperechnaya skorost' - 61 km/s. Dlya pul'sara B1929+10 polucheny znacheniya pi=(2.77+/-0.07)x10-3 " (d=361+/-8 pk), a poperechnaya skorost' - 177+/-5 km/s. miniobzor astro-ph/0312050 Magnitogidrodinamicheskie dzhety Sverhnovyh: propushennoe zveno (MHD Supernova Jets: The Missing Link) Authors: David L.

Samymi vazhnymi napravleniyami avtory schitayut sleduyushie: dzhety obrazuyutsya v techenie neskol'kih sekund posle kollapsa yadra sverhnovoi; dzhety otvetstvenny za asimmetriyu kollapsa sverhnovoi v celom. Avtory schitayut, chto v formirovanii dzhetov osnovnymi yavlyayutsya elektrodinamicheskie processy. astro-ph/0312059 Proekt Skysoft (The Skysoft Project) Authors: C. Baffa, E. Giani, A.

Comments: 9 pages, 10 figures Chtoby izbavit'sya ot fona kosmicheskih luchei na cherenkovskih detektorah chastic sverhvysokih energii (vodyanyh ili ledyanyh) obychno registriruyut chasticy, kotorye idut snizu, t.e. pered etim ishodnaya chastica peresekaet vsyu Zemlyu, a registriruemaya zaryazhennaya chastica rozhdaetsya gde-to neposredstvenno pod detektorom. Odnako dlya polucheniya tochnyh rezul'tatov trebuetsya znat' kak ishodnye chasticy (neitrino) rasprostranyayutsya v tolshe Zemli.
