Gravitational-Wave Radiation from Magnetized Accretion Disks
S. Mineshige, T. Hosokawa, M. Machida +1
The detectability of gravitational wave (GW) radiation from accretion disks is discussed based on various astrophysical contexts. In order to emit GW radiation, the disk shape shou…
Log-Normal Distributions in Cygnus X-1: Possible Physical Link with Gamma-Ray Bursts and Blazars
H. Negoro, S. Mineshige
Prompted by recent discoveries of log-normal distributions in gamma-ray/X-ray temporal variabilities of gamma-ray bursts (GRBs) and blazars, we re-examine the X-ray variability of…
Two-temperature coronal flow above a thin disk
B. F. Liu, S. Mineshige, F. Meyer +2
We extended the disk corona model (Meyer & Meyer-Hofmeister 1994; Meyer, Liu, & Meyer-Hofmeister 2000a) to the inner region of galactic nuclei by including different temperatures i…
Does the Slim-Disk Model Correctly Consider Photon-Trapping Effects?
Ken Ohsuga, Shin Mineshige, Masao Mori +1
We investigate the photon-trapping effects in the super-critical black hole accretion flows by solving radiation transfer as well as the energy equations of radiation and gas. It i…
Can neutrino-cooled accretion disk be an origin of gamma-ray bursts?
Kazunori Kohri, Shin Mineshige
It is often considered that a massive torus with solar mass or so surrounding a stellar-mass black hole may be a central engine of a gamma-ray burst. We study the properties of suc…
