dc.description.abstract | We present the results of our photometric and spectroscopic studies of the new eclipsing cataclysmic variable star 1RXS J180834. 7+101041. Its spectrum exhibits double-peaked hydrogen and helium emission lines. The Doppler maps constructed from hydrogen lines show a nonuniform distribution of emission in the disk similar to that observed in IP Peg. This suggests that the object can be a cataclysmic variable with tidal density waves in the disk. We have determined the component masses (M WD = 0.8 ± 0.22M ⊙ and M RD = 0.14 ± 0.02M ⊙) and the binary inclination (i = 78° ± 1.5°) based on well-known relations between parameters for cataclysmic variable stars. We have modeled the binary light curves and showed that the model of a disk with two spots is capable of explaining the main observed features of the light curves. © 2011 Pleiades Publishing, Ltd. | |
