Advective accretion disks and related problems including magnetic fields

GS Bisnovatyi-Kogan, RVE Lovelace - New Astronomy Reviews, 2001‏ - Elsevier
Accretion disk theory was first developed assuming local heat balance where the energy
produced by viscous heating was emitted from the sides of the disk. One of the important …

Supercritical accretion flows around black holes: two-dimensional, radiation pressure-dominated disks with photon trap**

K Ohsuga, M Mori, T Nakamoto… - The Astrophysical …, 2005‏ - iopscience.iop.org
The quasi-steady structure of supercritical accretion flows around a black hole is studied
based on two-dimensional radiation-hydrodynamic (2D-RHD) simulations. The supercritical …

Zero-energy rotating accretion flows near a black hole

D Ryu, SK Chakrabarti, D Molteni - The Astrophysical Journal, 1997‏ - iopscience.iop.org

Viscous accretion discs around rotating black holes

J Peitz, S Appl - Monthly Notices of the Royal Astronomical …, 1997‏ - academic.oup.com
The stationary hydrodynamic equations for transonic viscous accretion discs in Kerr
geometry are derived. A consistent formulation is given for the viscous angular momentum …

Rotating accretion flows: From infinity to the black hole

J Li, J Ostriker, R Sunyaev - The Astrophysical Journal, 2013‏ - iopscience.iop.org
Accretion onto a supermassive black hole of a rotating inflow is a particularly difficult
problem to study because of the wide range of length scales involved. There have been …

Spectral properties of accretion disks around black holes. II. Sub-Keplerian flows with and without shocks

SK Chakrabarti - The Astrophysical Journal, 1997‏ - iopscience.iop.org
Close to a black hole, the density of the sub-Keplerian accreting matter becomes higher
compared with a spherical flow as a consequence of the presence of a centrifugal barrier …

Influence of ohmic heating on advection-dominated accretion flows

GS Bisnovatyi-Kogan, RVE Lovelace - The Astrophysical Journal, 1997‏ - iopscience.iop.org
Abstract Advection-dominated, high-temperature, quasi-spherical accretion flow onto a
compact object, recently considered by a number of authors, assumes that the dissipation of …

Estimation of mass of compact object in H 1743-322 from 2010 and 2011 outbursts using TCAF solution and spectral index–QPO frequency correlation

The well-known black hole candidate (BHC) H 1743-322 exhibited temporal and spectral
variabilities during several outbursts. The variation of the accretion rates and flow geometry …

Accretion flow dynamics of MAXI J1836-194 during its 2011 outburst from TCAF solution

A Jana, D Debnath, SK Chakrabarti… - The Astrophysical …, 2016‏ - iopscience.iop.org
The Galactic transient X-ray binary MAXI J1836-194 was discovered on 2011 August 29.
Here we make a detailed study of the spectral and timing properties of its 2011 outburst …

Properties of accretion shock waves in viscous flows around black holes

SK Chakrabarti, S Das - Monthly Notices of the Royal …, 2004‏ - academic.oup.com
Accretion flows having low angular momentum and low viscosity can have standing shock
waves. These shocks arise because of the presence of multiple sonic points in the flow. We …
