Universal behaviour of $α$ -viscosity in black hole accretion discs

Marek A. Abramowicz, Axel Brandenburg, Jiří Horák +4

The Shakura-Sunyaev $α$ -viscosity coefficient, defined as the ratio of total stress to total pressure, $α = T / p$ , began to play an important role in the development of accr…

Polarization from the oscillating magnetized accretion torus

Jiri Horak, Michal Bursa

We study oscillations of accretion torus with azimuthal magnetic field. For several lowest-order modes we calculate eigenfrequencies and eigenfunctions and calculate corresponding…
