Application of a new X-ray reflection model to V1223 Sagittarii
Takayuki Hayashi, Takao Kitaguchi, Manabu Ishida
In intermediate polars (IPs), the intrinsic thermal emissions from white dwarfs (WDs) have typically been studied. Few reports have analyzed X-ray reflections from WDs. We recently…
An Estimation of the White Dwarf Mass in the Dwarf Nova GK Persei with NuSTAR Observations of Two States
Yuuki Wada, Takayuki Yuasa, Kazuhiro Nakazawa +3
We report on X-ray observations of the Dwarf Nova GK Persei performed by {\it NuSTAR} in 2015. GK Persei, behaving also as an Intermediate Polar, exhibited a Dwarf Nova outburst in…
X-ray reflection from cold white dwarfs in magnetic cataclysmic variables
Takayuki Hayashi, Takao Kitaguchi, Manabu Ishida
We model X-ray reflection from white dwarfs (WD) in magnetic cataclysmic variables (mCVs) with a Monte Carlo simulation. A point source with a power-law spectrum or a realistic pos…
Modeling Dipolar Post-Shock Accretion Columns for Various Specific Accretion Rate Intermediate Polars
T. Hayashi, M. Ishida
We model the post-shock accretion column (PSAC) for intermediate polars (IPs), with parameterizing specific accretion rate between 0.0001 and 100 g cm-2 s-1 and metal abundance bet…
Broad-band properties of the hard X-ray cataclysmic variables IGR J00234+6141 and 1RXS J213344.1+510725
G. Anzolin, D. de Martino, M. Falanga +5
A significant number of cataclysmic variables were detected as hard X-ray sources in the INTEGRAL survey, most of them of the magnetic intermediate polar type. We present a detaile…
Super-hard X-Ray Emission from eta Carinae Observed with Suzaku
Akiko Sekiguchi, Masahiro Tsujimoto, Shunji Kitamoto +4
We present the Suzaku results of eta Carinae in the 5--50 keV range conducted twice around the apastron in 2005 August for 50 ks and in 2006 February for 20 ks. The X-ray Imaging S…
