摘要：
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 lambda 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 (M (WD) = 0.54 +/- 0.10M (aS (TM)) andM (RD) = 0.45 +/- 0.05 M (aS (TM))) and the orbital inclination of the system (i = 71.8A degrees +/- 0.7A degrees) have been determined from observational data using well-known relations for close binaries and cataclysmic variable stars.
