The regularization of pair collisions for stars (material points) moving in three-dimensional space is carried out. It is assumed that a certain part of the stars moves in a spherical homogeneous cloud (the nucleus) of given density, while another part of the stars moves in a homogeneous concentric spherical layer (the corona) surrounding the nucleus and having a smaller density; the remaining stars move in free space. The KS transformation is used to obtain regular differential equations of motion, which are used to study the evolution of particular stellar systems.
