General relativistic accretion with backreaction
Janusz Karkowski, Bogusz Kinasiewicz, Patryk Mach +2
The spherically symmetric steady accretion of polytropic perfect fluids onto a black hole is the simplest flow model that can demonstrate the effects of backreaction. Backreaction…
From polytropic to barotropic perfect fluids in general-relativistic hydrodynamics
Bogusz Kinasiewicz, Patryk Mach
Two general-relativistic hydrodynamical models are considered: a model of self-gravitating static configurations of perfect fluid and a model of steady accretion of fluid onto a bl…
Selfgravitation in a general-relativistic accretion of steady fluids
Bogusz Kinasiewicz, Patryk Mach, Edward Malec
The selfgravity of an infalling gas can alter significantly the accretion of gases. In the case of spherically symmetric steady flows of polytropic perfect fluids the mass accretio…
Universality and backreaction in a general-relativistic accretion of steady fluids
Janusz Karkowski, Bogusz Kinasiewicz, Patryk Mach +2
The spherically symmetric steady accretion of polytropic perfect fluids onto a black hole is the simplest flow model that can demonstrate the effects of backreaction. The analytic…
Comparison of Two Stationary Spherical Accretion Models
Bogusz Kinasiewicz, Tomasz Lanczewski
The general relativistic accretion onto a black hole is investigated in which the motion is steady and spherically symmetrical, the gas being at rest at infinity. Two models with d…
