Pulse-amplitude-resolved spectroscopy of bright accreting pulsars: indication of two accretion regimes
X-ray binaries – neutron stars – accretion
2011/10/8
Context: In addition to coherent pulsation, many accreting neutron stars exhibit flaring activity and strong aperiodic variability on time scales comparable to or shorter than their pulsation period. ...
Analytic solutions to the accretion of a rotating finite cloud towards a central object - II. Schwarzschild spacetime
accretion, accretion discs, black hole physics, hydrodynamics, relativistic processes
2011/9/30
We construct a general relativistic model for the accretion flow of a rotating finite cloud of non-interacting particles infalling onto a Schwarzschild black hole. The streamlines start at a spherical...

The X-ray irradiated gas around a compact object was investigated. Wesolved the hydrostatic balance coupling with the ionization and thermal balancesto obtain the structure of the optically thin emiss...
Fast Transition between High-soft and Low-soft States in GRS 1915 C 105：Evidence for a Critically Viscous Accretion Flow
accretion discs binaries black hole X-rays
2009/5/19
We present the results of a detailed analysis of RXTE observations
of class ! (Klein-Wolt et al. 2002) which show an unusual state
transition between high-soft and low-soft states in the Galactic mi...
THE GRAVITATIONAL MICROLENS INFLUENCE ON X-RAY SPECTRAL LINE GENERATED BY AN AGN ACCRETION DISC
GRAVITATIONAL MICROLENS X-RAY SPECTRAL LINE AGN ACCRETION DISC
2009/3/13
The influence of gravitational microlensing on the X-ray spectral
line profiles originated from a relativistic accretion disc has been studied. Using
a disc model, we show that microlensing can indu...
