[vsnet-newvar 9497] TCP J22032951+3544161: new SU UMa-type dwarf nova
by Taichi Kato 09 Nov '22

09 Nov '22

TCP J22032951+3544161: new SU UMa-type dwarf nova According to the most recent observations by the Kyoto U. team (Nov. 6-8), this object started to show superhumps with a period of 0.06428(8) d (amplitude 0.10 mag). A shorter one-day alias is still possible. Early superhumps were below the detection limit as from the available observations. This object may be classified as an WZ Sge star later based on rebrightening(s). Itoh-san and Kiyota-san contributed in the earlier stage of the outburst.
