Abstract

This paper presents a determination of the parameters of the low accretion rate polar V379 Vir. Using data from the ground-based and space observatories, we obtained the spectral energy distribution in a wide spectral range, corrected for interstellar absorption. Modeling this distribution allowed us to determine the mass and effective temperature of the white dwarf: M1 = 0.628 ± 0.009 M⊙, Teff = 11250 ± 70 K. Based on the semi-amplitude of the radial velocities of the secondary component’s irradiated surface, we estimated its mass M2 ≈ 0.027 M⊙ and the inclination of the orbital plane i = 50 ± 5°.

Keywords: cataclysmic variables, novae, stars: individual: V379 Vir
