Dragging and anti-dragging effects in rotating disk systems

Details

Written by Michal Piróg

I will discuss hydrodynamical post-Newtonian models of self-gravitating stationary black-hole-disk systems. The recently discovered new class of rotation laws, which contain the general-relativistic extension of Newtonian rotation law, was applied to obtain the solution. There is strong numerical evidence that various types of dragging (anti-dragging) effects are positively correlated with the normalized angular momentum. I am going to present the numerical results for many different numerical models which show the relation between the above-mentioned effects and such parameters of the system like total mass and asymptotic angular momentum.
