Fully self-consistent nova explosion models reproducing light curves of KT Eri, V339 Del, V597 Pup, and SMC NOVA 2016-10a
Mariko Kato, Izumi Hachisu, Hideyuki Saio
The rising phase toward the optical maximum of a classical nova is one of the last frontiers of nova study. Constructing free-free emission model light curves based on our fully se…
A comprehensive light curve model of the very fast nova V1674 Herculis
Mariko Kato, Izumi Hachisu, Hideyuki Saio
V1674 Her is one of the fastest novae, of which the very early phase is well observed including optical rise to the peak over 10 magnitudes. We present a full theoretical light cur…
Linear adiabatic analysis for general relativistic instability in primordial accreting supermassive stars
Hideyuki Saio, Devesh Nandal, Sylvia Ekstroem +1
Accreting supermassive stars of will eventually collapse directly to a black hole via the general relativistic (GR) instability. Such direct collapses of…
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 helium nova in the Large Magellanic Cloud -- the faint supersoft X-ray source [HP99]159
Mariko Kato, Izumi Hachisu, Hideyuki Saio
We propose a helium nova model for the Large Magellanic Cloud (LMC) supersoft X-ray source (SSS) [HP99]159. This object has long been detected as a faint and persistent SSS for abo…
Unresolved Rossby and gravity modes in 214 A and F stars showing rotational modulation
Andreea I. Henriksen, Victoria Antoci, Hideyuki Saio +9
Here we report an ensemble study of 214 A- and F-type stars observed by \textit{Kepler}, exhibiting the so-called \textit{hump and spike} periodic signal, explained by Rossby modes…
