[vsnet-alert 27099] ZTF22abteqxm: new WZ Sge-type dwarf nova
by Taichi Kato 20 Nov '22

20 Nov '22

ZTF22abteqxm: new WZ Sge-type dwarf nova According to Itoh-san's observations on Nov. 18, this object showed superhumps with a period of 0.0580(4) d (single-night baseline). They were not very apparent on Nov. 17 in Kyoto U. team observations. An analysis of earlier data yielded a period of 0.05630(3) d with an amplitude of 0.04 mag. These modulations appear to be early superhumps. Observers are Kyoto U. team, Itoh-san, Josch Hambsch and Tamas Tordai.
