Analysis of the IW And star ASAS J071404+7004.3
Taichi Kato, Kiyoshi Kasai, Elena P. Pavlenko +14
We made a time-resolved photometric campaign of the bright cataclysmic variable ASAS J071404+7004.3 in 2020. Inight et al. (2022, arXiv/2109.14514) recently published time-resolved…
On the nature of the anomalous event in 2021 in the dwarf nova SS Cygni and its multi-wavelength transition
Mariko Kimura, Shinya Yamada, Nozomi Nakaniwa +20
SS Cyg has long been recognized as the prototype of a group of dwarf novae that show only outbursts. However, this object has entered a quite anomalous event in 2021, which at firs…
First Detection of Two Superoutbursts during Rebrightening Phase of a WZ Sge-type Dwarf Nova: TCP J21040470+4631129
Yusuke Tampo, Kojiguchi Naoto, Keisuke Isogai +51
We report photometric and spectroscopic observations and analysis of the 2019 superoutburst of TCP J21040470+4631129. This object showed a 9-mag superoutburst with early superhumps…
The 2015 superoutburst of QZ Virginis: Detection of growing superhumps between the precursor and main superoutburst
Akira Imada, Taichi Kato, Keisuke Isogai +9
We report on time-resolved photometry of the 2015 February-March superoutburst of QZ Virginis. The superoutburst consisted of a separated precursor, main superoutburst, and rebrigh…
ASASSN-16eg: New candidate of long-period WZ Sge-type dwarf nova
Yasuyuki Wakamatsu, Keisuke Isogai, Mariko Kimura +19
We report on our photometric observations of the 2016 superoutburst of ASASSN-16eg. This object showed a WZ Sge-type superoutburst with prominent early superhumps with a period of…
RZ Leonis Minoris Bridging between ER Ursae Majoris-Type Dwarf Nova and Novalike System
Taichi Kato, Ryoko Ishioka, Keisuke Isogai +64
We observed RZ LMi, which is renowned for the extremely (~19d) short supercycle and is a member of a small, unusual class of cataclysmic variables called ER UMa-type dwarf novae, i…
Study of Negative and Positive Superhumps in ER Ursae Majoris
Tomohito Ohshima, Taichi Kato, Elena Pavlenko +45
We carried out the photometric observations of the SU UMa-type dwarf nova ER UMa during 2011 and 2012, which showed the existence of persistent negative superhumps even during the…
Discovery of Negative Superhumps during a Superoutburst of January 2011 in ER Ursae Majoris
Tomohito Ohshima, Taichi Kato, Elena P. Pavlenko +19
We report on a discovery of "negative" superhumps during the 2011 January superoutburst of ER UMa. During the superoutburst which started on 2011 January 16, we detected negative s…
The 9 Aurigae System
K. Krisciunas, C. Aspin, T. R. Geballe +8
The F0 V star 9 Aur A exhibits an irregular variability of amplitude 0.1 magnitude at optical wavelengths. The variations are too slow for it to be a Scuti-type star.…
