  The Euler equation has been accepted as the basic postulate of stellar
physics long before the plasma physics was developed. The existence of
electrical interaction between particles of interstellar plasma poses the
question, how this interaction must be accounted for. We argue that the right
way is in formulation of a new postulate. On the base of the new postulate, the
theory of a hot star interior is developed. Using this theory we obtain the
distribution of stars over their masses and mass-radius, mass-temperature and
mass-luminosity dependencies. The theory of the apsidal rotation of binary
stars and the spectrum of solar oscillation is considered. All these
theoretical predictions are in a good agreement with the known measurement
data, which confirms the validity of this consideration.
