Oscillation modes of thick accretion disks using finite-elements calculations

21 Oct 2020, 13:25


Jiri Horak (Astronomical Institute ASCR, Prague)


We will present results for oscillation modes of thick accretion tori in Kerr spacetime using finite-element numerical method. We will derive relativistic version of the Papaloizou-Pringle equation for disks with general angular momentum distribution. Then we focus on the case of constant angular momentum tori and compare our results with those previously found by analytic perturbation methods.
