ABSTRACT: A two-body regularization for N-body
problem based on perturbation theory for Keplerian problem is discussed. We
provide analytical estimations of accuracy and conduct N-body experiments in
order to compare it with state-of-the-art Hermite integrator. It is shown that
this regularization keeps some features that allow overcoming KS-regularization
in some particular cases.
