Bondi-Hoyle accretion configurations occur as soon as a gravitating body is immersed in an ambient medium with a supersonic relative velocity. From wind-accreting X-ray binaries to runaway neutron stars, such a regime has been witnessed many times and is believed to account for shock formation, the properties of which can be only marginally derived analytically. In this paper, we present the first results of the numerical characterization of the stationary flow structure of Bondi-Hoyle…

Bondi–Hoyle–Lyttleton Accretion onto Star Clusters

An isolated star moving supersonically through a uniform gas accretes material from its gravitationally induced wake. The rate of accretion is set by the accretion radius of the star and is well

Wind accretion onto compact objects

X-ray emission associated to accretion onto compact objects displays important levels of photometric and spectroscopic time-variability. When the accretor orbits a Supergiant star, it captures a

Relativistic wind accretion on to a Schwarzschild black hole

We present a novel analytic model of relativistic wind accretion on to a Schwarzschild black hole. This model constitutes a general relativistic extension of the classical model of wind accretion by

Formation of wind-captured disks in supergiant X-ray binaries

Context. In supergiant X-ray binaries (SgXB), a compact object captures a fraction of the wind of an O/B supergiant on a close orbit. Proxies exist to evaluate the efficiency of mass and angular

Bondi or not Bondi: The impact of resolution on accretion and drag force modelling for Supermassive Black Holes

Whilst in galaxy-size simulations, supermassive black holes (SMBH) are entirely handled by sub-grid algorithms, computational power now allows the accretion radius of such objects to be resolved in

Accretion from a clumpy massive-star wind in supergiant X-ray binaries

Supergiant X-ray Binaries (SgXB) host a compact object, often a neutron star (NS), orbiting an evolved O/B star. Mass transfer proceeds through the intense line-driven wind of the stellar donor, a

Clumpy wind accretion in Supergiant X-ray Binaries

Abstract Supergiant X-ray Binaries host a compact object, generally a neutron star, orbiting an evolved O/B star. Mass transfer proceeds through the intense radiatively-driven wind of the stellar

Wind Roche lobe overflow in high-mass X-ray binaries

Ultraluminous X-ray sources (ULXs) have such high X-ray luminosities that they were long thought to be accreting intermediate-mass black holes. Yet, some ULXs have been shown to display periodic

Wind morphology around cool evolved stars in binaries

Context. The late evolutionary phase of low- and intermediate-mass stars is strongly constrained by their mass-loss rate, which is orders of magnitude higher than during the main sequence. The wind

Radiative GRMHD simulations of accretion and outflow in non-magnetized neutron stars and ultraluminous X-ray sources

We run two GRRMHD simulations of super-Eddington accretion disks around a black hole and a neutron star. We observe the formation of a boundary layer in the neutron star simulation which leads to a



Axisymmetric Bondi–Hoyle accretion on to a Schwarzschild black hole: shock cone vibrations

We study numerically the axisymmetric relativistic Bondi–Hoyle accretion of a supersonic ideal gas on to a fixed Schwarzschild background space–time described with horizon penetrating coordinates. We

Bondi-Hoyle Accretion in a Turbulent Medium

The Bondi-Hoyle formula gives the approximate accretion rate onto a point particle accreting from a uniform medium. However, in many situations accretion onto point particles occurs from media that


In this work, for the first time, we present a numerical study of Bondi–Hoyle accretion with density gradients in the fully relativistic regime. In this context, we consider the accretion onto a Kerr

Three-dimensional hydrodynamic Bondi-Hoyle accretion. 1: Code validation and stationary accretors

We investigate the hydrodynamics of three-dimensional classical Bondi-Hoyle accretion. Totally absorbing stationary spheres of varying sizes (from 10.0 down to 0.02 Bondi radii) accrete matter from a

A Numerical Study of Relativistic Bondi-Hoyle Accretion onto a Moving Black Hole: Axisymmetric Computations in a Schwarzschild Background

A fully relativistic numerical study of nonspherical Bondi-Hoyle accretion onto a Schwarzschild black hole is presented. The simulations are performed in axisymmetry with a high-resolution

Three-dimensional hydrodynamic Bondi-Hoyle accretion. 2: Homogeneous medium at Mach 3 with gamma = 5/3

We investigate the hydrodynamics of three-dimensional classical Bondi-Hoyle accretion. Totally absorbing spheres of varying sizes (from 10 down to 0.01 accretion radii) move at Mach 3 relative to a

An investigation of the stability of the Bondi-Hoyle model of accretion flow. [onto massive astronomical bodies at high Mach number

The Bondi-Hoyle-Lyttleton (1944) accretion model is considered which involves accretion onto a massive body moving at a high Mach number with respect to the ambient medium and the production of a

Bondi Accretion in the Presence of Vorticity

The classical Bondi-Hoyle formula gives the accretion rate onto a point particle of a gas with a uniform density and velocity. However, the Bondi-Hoyle problem considers only gas with no net


We investigate the stability of gravitational accretion of an ideal gas onto a compact object moving through a uniform medium at Mach 3. Previous three-dimensional simulations have shown that such

Three-dimensional Magnetohydrodynamic Simulations of Spherical Accretion

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
