0064 | Three new variable stars in the field of the RR Lyrae star AK Gem 1472 kB | F.-J. HAMBSCH | | 2007-05-23 | | Three new variable stars (HMB06 = USNO-B1.0 1035-0121819, HMB07 = USNO-B1.0 1036-0121306 and HMB08 = USNO-B1.0 1035-0121640) have been identified in the field of the RR Lyrae type variable AK Gem. Full light curves for all the three stars are presented. The form of the light curve indicates that all the three stars are EW type variable stars. For HMB06 a period P = 0.32667 +/- 0.00012 [d] with the epoch E0 = HJD 2454155.699 and an amplitude of the light variation of dm = 0.6 +/- 0.1 mag. has been found. For HMB07 a period P = 0.53284 +/- 0.00017 [d] with the epoch E0 = HJD 2454155.683 and an amplitude of the light variation of dm = 0.45 +/- 0.05 mag has been found. And finally for HMB08 a period P = 0.43257 +/- 0.00024 [d] with the epoch E0 = HJD 2454155.742 and an amplitude of the light variation of dm = 0.25 +/- 0.1mag. has been found. Objekty Simbad: USNO-B1.0 1035-0121640, USNO-B1.0 1036-0121306, USNO-B1.0 1035-0121819, | komentáře: 0 |
