Results of photometric and spectroscopic studies for the new eclipsing cataclysmic variable star HBHA 4705-03 with an orbital period of 0. 1718 days are presented. Its spectrum exhibits hydrogen and helium emission lines. The Doppler maps constructed from hydrogen lines and the He II λ 4686 line show that the regions near the inner Lagrangian point are the main source of emission in these lines, while the maps constructed from He I lines suggest the presence of an accretion disk around the primary. The masses of the components (MWD = 0. 54 ± 0. 10M⊙ andMRD = 0. 45 ± 0. 05 M⊙) and the orbital inclination of the system (i = 71. 8° ± 0. 7°) have been determined from observational data using well-known relations for close binaries and cataclysmic variable stars. © 2013 Pleiades Publishing, Ltd. |
