}We study the short- and long-term effects of an intermediate mass black hole (IMBH) on the orbits of stars bound to the supermassive black hole (SMBH) at the center of the Milky Way. A regularized N-body code including post-Newtonian terms is used to carry out direct integrations of 19 stars in the S-star cluster for 10 Myr. The mass of the IMBH is assigned one of four values from 400 M ☉ to 4000 M ☉, and its initial semimajor axis with respect to the SMBH is varied from 0.3 to 30 mpc… CONTINUE READING
