2021 superoutburst of WZ Sge-type dwarf nova V627 Pegasi lacks an early superhump phase

Yusuke Tampo, Taichi Kato, Naoto Kojiguchi +27

Superoutbursts in WZ Sge-type dwarf novae (DNe) are characterized by both early superhumps and ordinary superhumps originating from the 2:1 and 3:1 resonances, respectively. Howeve…

OT J002656.6+284933 (CSS101212:002657+284933): An SU UMa-Type Dwarf Nova with Longest Superhump Period

Taichi Kato, Tamas Tordai, Colin Littlefield +17

We observed the 2016 outburst of OT J002656.6+284933 (CSS101212:002657+284933) and found that it has the longest recorded [0.13225(1) d in average] superhumps among SU UMa-type dwa…

Superoutburst of WZ Sge-type Dwarf Nova Below the Period Minimum: ASASSN-15po

Kosuke Namekata, Keisuke Isogai, Taichi Kato +38

We report on a superoutburst of a WZ Sge-type dwarf nova (DN), ASASSN-15po. The light curve showed the main superoutburst and multiple rebrightenings. In this outburst, we observed…
