Universal behaviour of -viscosity in black hole accretion discs
Marek A. Abramowicz, Axel Brandenburg, Jiří Horák +4
The Shakura-Sunyaev -viscosity coefficient, defined as the ratio of total stress to total pressure, , began to play an important role in the development of accr…
Broad Iron Line as a Relativistic Reflection from Warm Corona in AGN
P. P. Biswas, A. Różańska, F. H. Vincent +2
We present that the broad feature usually observed in X-ray spectra can be explained by a ray-traced emission from a two-slab system containing a dissipative, warm corona on top of…
Accretion tori around rotating neutron stars II: Oscillations and precessions
Monika Matuszková, Gabriel Török, Kateřina Klimovičová +7
The four characteristic oscillation frequencies of accretion flows are, in addition to the Keplerian orbital frequency, often discussed in the context of the time variability of th…
Accretion tori around rotating neutron stars I: Structure, shape and size
Monika Matuszková, Gabriel Török, Debora Lančová +7
We present a full general relativistic analytic solution for a radiation-pressure supported equilibrium fluid torus orbiting a rotating neutron star (NS). Previously developed anal…
