Shocks in the relativistic transonic accretion with low angular momentum
Abstract We perform 1D/2D/3D relativistic hydrodynamical simulations of accretion flows
with low angular momentum, filling the gap between spherically symmetric Bondi accretion …

Propagating mass accretion rate fluctuations in X-ray binaries under the influence of viscous diffusion
AA Mushtukov, A Ingram… - Monthly Notices of the …, 2018 - academic.oup.com
Many statistical properties of X-ray aperiodic variability from accreting compact objects can
be explained by the propagating fluctuations model applied to the accretion disc. The mass …

Near-horizon structure of escape zones of electrically charged particles around weakly magnetized rotating black hole
O Kopáček, V Karas - The Astrophysical Journal, 2018 - iopscience.iop.org
An interplay of magnetic fields and gravitation drives accretion and outflows near black
holes. However, a specific mechanism is still a matter of debate; it is very likely that different …
