The light curve simulations of the 2021 anomalous event in SS Cygni
Mariko Kimura, Yoji Osaki
The prototype dwarf nova SS Cyg unexpectedly exhibited an anomalous event in its light curve in the early few months of 2021 in which regular dwarf nova-type outbursts stopped, but…
KIC 9406652: A laboratory for tilted disks in cataclysmic variable stars. II. Modeling of the orbital light curves
Mariko Kimura, Yoji Osaki
KIC 9406652, one of the recently identified IW And-type dwarf novae, is the best target for studying the tilted disk in cataclysmic variable stars. In a previous paper by Kimura, O…
KIC 9406652: A laboratory of the tilted disk in cataclysmic variable stars
Mariko Kimura, Yoji Osaki, Taichi Kato
KIC 9406652 is a cataclysmic variable (CV), sub-classified as `IW And-type star', showing a repetition of standstills with oscillatory variations terminated by brightening. This sy…
Thermal-viscous instability in tilted accretion disks: a possible application to IW And-type dwarf novae
Mariko Kimura, Yoji Osaki, Taichi Kato +1
IW And stars are a subgroup of dwarf novae characterized by repetitive light variations of the intermediate-brightness state with oscillations, which is terminated by brightening.…
GALEX J194419.33+491257.0: An Unusually Active SU UMa-Type Dwarf Nova with a Very Short Orbital Period in the Kepler Data
Taichi Kato, Yoji Osaki
We studied the background dwarf nova of KIC 11412044 in the Kepler public data and identified it with GALEX J194419.33+491257.0. This object turned out to be a very active SU UMa-t…
KIC 7524178 -- an SU UMa-Type Dwarf Nova Showing Predominantly Negative Superhumps throughout Supercycle
Taichi Kato, Yoji Osaki
We analyzed the Kepler long cadence data of KIC 7524178 (=KIS J192254.92+430905.4), and found that it is an SU UMa-type dwarf nova with frequent normal outbursts. The signal of the…
