| Abstract: |
Results of photometric and spectroscopic investigations of the recently
discovered eclipsing cataclysmic variable star HBHA 4705–03 are
presented.
The emission spectra of the system show broad hydrogen and
helium emission lines. The bright spots with an approximately zero velocity components are found
in the Doppler maps for the hydrogen and ionized helium lines. The disc structure is more prominent in the maps
for the neutral helium lines.
The masses of the components (MWD = 0.54 ± 0.10M☉ and
MRD = 0.45 ± 0.05 M☉), and the orbit inclination
(i = 71.°8 ± 0.°7) were estimated using the radial velocity light curve and the eclipse width.
The modeling of the light curve allows us to evaluate the bright
spot parameters and the mass accretion rate (M ≈ 2 ·1017 g s-1). |
