Luminosity, redshift and gas abundance in general relativistic radiation hydrodynamics
Janusz Karkowski, Edward Malec, Krzysztof Roszkowski +1
Quasi-stationary flows of gas accreting onto a compact center are analyzed in the framework of general-relativistic radiation hydrodynamics, under assumptions of spherical symmetry…

Gravastars and bifurcation in quasistationary accretion
Edward Malec, Krzysztof Roszkowski
We investigate the newtonian stationary accretion of a polytropic perfect fluid onto a central body with a hard surface. The selfgravitation of the fluid and its interaction with l…
