Abstract: A new equation of state for hot white dwarfs of small and intermediate masses, which takes into account the contribution of an ideal relativistic electron subsystem, the contribution of a gas nuclear subsystem, and the light pressure was proposed. The internal structure of dwarfs was calculated within such model. It was shown that the proposed model agrees with the observed distribution of white dwarfs on the mass-radius plane. Based on the observed data on masses and radii of white dwarfs, there was solved the inverse problem -- the determination of model parameters for the specific stars.
