Deminova, N.R. Investigation of the pre-cataclysmic variable NSVS 14256825 / N.R Deminova, V.V Shimanskii, I.F. Bikmaev, N.V Borisov, M.M. Gabdeev // Astronomical journal of Azerbaijan. – 2020. – V.15, № 2. – P.53-58

Annotation

In this work, we studied the features of the formation of radiation from the young pre-cataclysmic variable NSVS 14256825. The theoretical phase light curves of the system are matched taking into account the effects of reflection and non-sphericity of the components with those observed in the BVR bands. From the analysis of moderate-resolution spectra, a radial velocity curve of the sdB sub-dwarf was constructed and estimates of its amplitude were found. The integrated spectra of the system were simulated and the weakness of the effects of reflection on the deformation of the radial velocity curve of the sdB – sub-dwarf was theoretically shown. Based on a comprehensive analysis of observational data, the fundamental parameters of NSVS 14256825 are determined.
