Bondi Accretion in Trumpet Geometries [PDF]
, 2016 The Bondi solution, which describes the radial inflow of a gas onto a non-rotating black hole, provides a powerful test for numerical relativistic codes.

Studying the Effect of Radiation Pressure on Evolution of a Population III Stellar Cluster
The Astrophysical JournalRecent numerical simulations have shown that the unstable disk within the central regime of the primordial gas cloud fragments to form multiple protostars on several scales.

Bondi-Hoyle accretion simulations including velocity gradients
, 1994 We investigate the hydrodynamics of three-dimensional classical Bondi-Hoyle accretion, especially the accretion of angular momentum from a non-homogeneous medium and discuss some consequences for models of wind-fed X-ray sources.

The Impact of Wind Accretion in Evolving Symbiotic Systems
The Astrophysical JournalWe investigate the impact of geometric corrections to the Bondi–Hoyle–Lyttleton (BHL) accretion scheme applied to evolving symbiotic systems. We model systems where 0.7 and 1 M _⊙ white dwarfs (WDs) accrete material from solar-like stars with initial ...

Bondi Accretion onto a Luminous Object
Spherical accretion of ionized gas onto a gravitating object is examined under the influence of central radiation. In classical Bondi accretion onto a non-luminous source with mass M, the accretion rate M_B is expressed as M_B = lambda(gamma) x 4piG^2M^2

Three‐dimensional Magnetohydrodynamic Simulations of Spherical Accretion
, 2019 We present three-dimensional numerical magnetohydrodynamic simulations of radiatively inefficient spherical accretion onto a black hole. The simulations are initialized with a Bondi flow and with a weak, dynamically unimportant, large-scale magnetic ...
