[vsnet-campaign-dn 17189] SDSS J094002.56+274942.0: another long-Porb SU UMa star
by Taichi Kato 20 Apr '23

20 Apr '23

SDSS J094002.56+274942.0: another long-Porb SU UMa star ZTF time-resolved data recorded superhumps during the 2019 Feb. outburst. T. Vanmunster's observation also detected 0.3-mag superhump(s) on 2019 Feb. 11. Probably due to the long Porb=0.16352 d, this variation was not regarded as superhump(s). The 2009 outburst (Krajci and Wils JAAVSO 38, 33) was a normal one. The secondary is probably somewhat evolved as reported as a possible spectral class early M-type in Krajci and Wils (2010).
