Twocomponent stellar systems in thermal and dynamical equilibrium
Abstract
Equilibrium families of finite, twocomponent stellar systems are constructed which satisfy equipartition of energy in their cores. The suggestion of Spitzer (1969), Lightman and Fall (1978), and others, that such equilibria are precluded if the mass in heavy stars exceeds a certain fraction of the total mass, is not supported by these models. This implies that the formation of contracting subsystems of heavy stars in stellar systems cannot be explained purely on the basis of equilibrium arguments.
