Abstract
The migration of central compact massive objects (CMO) in galactic nuclei caused by encounters with spherical clusters is studied. A CMO moves in the field of the fixed potential of a galactic bulge. An empirical relationship between the masses of a CMO and of a bulge (Mbh = 0.001 Mb) is used here. The dependence of the amplitude of the CMO drift on the mass and size of a bulge, as well as on the initial velocity and mass of a spherical cluster, is found. It is shown that, on the average, the drift amplitude increases as the size of a bulge increases (with its mass fixed) and decreases with increasing bulge mass (with its size fixed). The amplitude of the drift increases on the average with increasing cluster mass and decreasing cluster velocity.
