The equilibrium of a hot dense plasma in a gravitational field is considered. From the standard equilibrium equations, the energy minimum at density about $10^{ 25}$ particles per $cm^3$ and temperature about $10^7 K$ was found. This effect plays an important role for astrophysics. It enables to explain the mechanism of the star magnetic field generation and to make a prediction for the spectrum of a star mass with a wholly satisfactory agreement for the observation data.
