The Astrophysical Journal, 2023 We present global 3D radiation magnetohydrodynamic simulations of accretion onto a 6.62 solar-mass black hole, with quasi-steady-state accretion rates reaching 0.016–0.9 times the critical accretion rate, which is defined as the accretion rate for ...

ACCRETION DISKS WITH A LARGE SCALE MAGNETIC FIELD AROUND BLACK HOLES
Acta Polytechnica, 2013 We consider accretion disks around black holes at high luminosity, and the problem of the formation of a large-scale magnetic field in such disks, taking into account the non-uniform vertical structure of the disk.

Hoyle-Lyttleton Accretion onto Accretion Disks [PDF]
, 1999 We investigate Hoyle-Lyttleton accretion for the case where the central source is a luminous accretion disk. %In classical Hoyle-Lyttleton accretion onto a ``spherical'' source, accretion takes place in an axially symmetric manner around a so-called ...

On the Formation and Interaction of Multiple Supermassive Stars in Cosmological Flows
The Astrophysical Journal, 2023 Supermassive primordial stars with masses exceeding ∼10 ^5 M _⊙ that form in atomically cooled halos are the leading candidates for the origin of high-redshift quasars at z > 6.

Waves and Instabilities in Accretion Disks: MHD Spectroscopic Analysis [PDF]
, 2002 A complete analytical and numerical treatment of all magnetohydrodynamic waves and instabilities for radially stratified, magnetized accretion disks is presented. The instabilities are a possible source of anomalous transport. While recovering results on

Nucleosynthesis in the Outflow from Gamma Ray Burst Accretion Disks [PDF]
, 2005 We examine the nucleosynthesis products that are produced in the outflow from rapidly accreting disks. We find that the type of element synthesis varies dramatically with the degree of neutrino trapping in the disk and therefore the accretion rate of the

Accretion of Solid Materials onto Circumplanetary Disks from Protoplanetary Disks [PDF]
, 2014 We investigate accretion of solid materials onto circumplanetary disks from heliocentric orbits rotating in protoplanetary disks, which is a key process for the formation of regular satellite systems.

ACCRETION INTO BLACK HOLES WITH MAGNETIC FIELDS, AND RELATIVISTIC JETS
Odessa Astronomical Publications, 2011 We discuss the problem of the formation of a large-scale magnetic field in the accretion disks around black holes, taking into account the non-uniform vertical structure of the disk.

Tomographic Simulations of Accretion Disks in Cataclysmic Variables - Flickering and Wind [PDF]
, 2006 Both continuum and emission line flickering are phenomena directly associated with the mass accretion process. In this work we simulate accretion disk Doppler maps including the effects of winds and flickering flares.
