[vsnet-newvar 10078] Please also observe ASASSN-22ak (southern object)
by Taichi Kato 12 May '23

12 May '23

Please also observe ASASSN-22ak (southern object) Josch Hambsch has been reporting observations. The data, however, were not sampled sufficiently and it is difficult to find a period. There is a suggestion of a period of 0.0453 d (consistent with the rapid fading observed in the 2022 superoutburst?). This object underwent the first-known outburst in 2022 Jan. (long after a dormant period?) and repeated unusual outbursts since then. The current outburst is the fourth one. Although … [View More]

[vsnet-newvar 10077] Gaia DR3 2893005857946801152 = ASASSN-23dr: most likely WZ Sge star
by Taichi Kato 12 May '23

12 May '23

Gaia DR3 2893005857946801152 = ASASSN-23dr: most likely WZ Sge star Berto Monard and Josch Hambsch have reported observations. Using Monard's data, there appears to be a period of 0.05452(5) d with a double-peaked profile. The result, however, is preliminary since the amplitude was small (0.03 mag) and observations are still limited. I used the name Gaia DR3 2893005857946801152 since this object was selected as a variable by Gaia (there was probably simply no concept of a dwarf nova in … [View More]
