Abstract
In this work, the optical radiation of the young pre-cataclysmic variable (PV) SDSS J162256 was investigated. Spectroscopic observations were carried out at BTA SAO RAS, photometric observations were carried out at RTT-150 telescope. Numerical modeling of theoretical light curves and spectra was done. The measured sets of radial velocities were analyzed taking into account the possible influence of reflection effects. The fundamental parameters of SDSS J162256 were determined based on a comprehensive analysis of observational data. It was shown that the previously proposed method for determining the masses of the PV components by modeling of the radial-velocity curves is effective only for systems with significant reflection effects.
