Semi-Analytical Model for Wind-Fed Black Hole High-Mass X-ray Binaries -- State Transition Triggered by Magnetic Fields from the Companion Star --
Kentaro Yaji, Shinya Yamada, Kuniaki Masai
We propose a mechanism of state transition in wind-fed black hole binaries (high-mass X-ray binaries) such as Cyg X-1 and LMC X-1. Modeling a line-driven stellar wind from the comp…
Multi-Year X-ray Variations of Iron-K and Continuum Emissions in the Young Supernova Remnant Cassiopeia A
Toshiki Sato, Yoshitomo Maeda, Aya Bamba +9
We found simultaneous decrease of Fe-K line and 4.2-6 keV continuum of Cassiopeia A with the monitoring data taken by Chandra in 2000-2013. The flux change rates in the whole remna…
L_X-T Relation and Related Properties of Galaxy Clusters
Naomi Ota, Tetsu Kitayama, Kuniaki Masai +1
An observational approach is presented to constrain the global structure and evolution of the intracluster medium based on the ROSAT and ASCA distant cluster sample. From statistic…
Quasi-hydrostatic intracluster gas under radiative cooling
Kuniaki Masai, Tetsu Kitayama
Quasi-hydrostatic cooling of the intracluster gas is studied. In the quasi-hydrostatic model, work done by gravity on the inflow gas with dP \neq 0, where P is the gas pressure, is…
