EVOLUTION OF ROTATION OF A NEARLY DYNAMICALLY SPHERICAL TRIAXIAL SATELLITE UNDER THE ACTION OF GRAVITATIONAL AND LIGHT TORQUES

摘要

We study the evolution of rotation of a rigid body (a Sun satellite moving in an elliptic orbit with arbitrary eccentricity) subjected to moments of gravitational forces and light pressure. The body is assumed to be nearly dynamically spherical, and its surface is assumed to be a surface of revolution, which allows one to approximate the light pressure torque coefficient by a finite trigonometric polynomial. In the first approximation of the averaging method, we obtain new qualitative effects of satellite rotation relative to its center of mass.
