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…
On the identity of Tsesevich's "YY Dra"
Taichi Kato, Elena P. Pavlenko
Hill et al. (2022, arXiv:2203.00221) recently published analysis of the intermediate polar DO Dra (YY Dra) using TESS, ASAS-SN and ZTF data. They also attempted a search for the "l…
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…
Orbital and spin periods of the candidate white dwarf pulsar ASASSN-V J205543.90+240033.5
Taichi Kato, Franz-Josef Hambsch, Elena P. Pavlenko +1
ASASSN-V J205543.90+240033.5 has been suggested to be a white dwarf pulsar by Kato (2021, arXiv:2108.09060). We obtained time-resolved photometry and identified the orbital and spi…
Optical Variability Correlated with X-ray Spectral Transition in the Black-Hole Transient ASASSN-18ey = MAXI J1820+070
Keito Niijima, Mariko Kimura, Yasuyuki Wakamatsu +49
How a black hole accretes matter and how this process is regulated are fundamental but unsolved questions in astrophysics. In transient black-hole binaries, a lot of mass stored in…
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…
