Physics

Scientific paper

We studied the conditions of occurrence of the resonant relaxation in small manybody systems. The timescale of resonant relaxation can be much shorter than the timescale of normal nonresonant relaxation depending on the mass ratio of the central massive object to the total mass of the stars around it. It means that we can get usable results using N-body simulations with not too many particles (up to two hundred particles typically) in relatively short CPU time. We present a set of simulations which are different in the mass ratio of the stars to the central black hole, the strengthness of post-Newtonian terms, whether the black hole was allowed to move or a fixed potential was used.
