[vsnet-campaign-dn 16861] TCP J06442271+1549388: new WZ Sge-type dwarf nova
by Taichi Kato 17 Jan '23

17 Jan '23

TCP J06442271+1549388: new WZ Sge-type dwarf nova Itoh-san and Kiyota-san have reported observations. The data show clear double-wave humps (amplitude 0.05 mag). The period was 0.0529(5) d (single-night baseline). Although The profile was somewhat different from those of typical WZ Sge-type early superhumps, the large outburst amplitude supports this classification.

Re: Spectrum of TCP J06442271+1549388 As judged from broad absorption features of H beta and higher lines, H alpha appears to be filled by emission and only the emission core is visible. I also see He II and Bowen.
