Gravitational Dynamics: Part II

Gravitational Dynamics: Part II. Non-Equilibrium systems. Lec12: Growth of a Black Hole by capturing objects in Loss Cone. A small BH on orbit with pericentre r p <R bh is lost (as a whole) in the bigger BH. The final process is at relativistic speed. Newtonian theory is not adequate
