A multiwavelength light curve analysis of the classical nova KT Eri: Optical contribution from a large irradiated accretion disk
Izumi Hachisu, Mariko Kato, Frederick M. Walter
KT Eri is a classical nova which went into outburst in 2009. Recent photometric analysis in quiescence indicates a relatively longer orbital period of 2.6 days, so that KT Eri coul…
X-Ray Flashes on Helium Novae
Mariko Kato, Izumi Hachisu
A helium nova occurs on a white dwarf (WD) accreting hydrogen-deficient matter from a helium star companion. When the mass of a helium envelope on the WD reaches a critical value,…
Physics of nova outbursts: Theoretical models of classical nova outbursts with optically thick winds on and white dwarfs
Mariko Kato, Hideyuki Saio, Izumi Hachisu
We present time-dependent nova outburst models with optically thick winds for a 1.2 and 1.35 white dwarfs (WDs) with a mass accretion rate of y…
A multiwavelength light curve model of the classical nova V339 Del: A mechanism for the coexistence of dust dip and supersoft X-rays
Izumi Hachisu, Mariko Kato, Katsura Matsumoto
The classical nova V339 Del 2013 is characterized by a 1.5 mag dip of the light curve owing to a dust shell formation, during which soft X-ray emissions coexist. We present Str…
