HBHA 4705-03: A new cataclysmic variable

Yakin D.; Suleimanov V.; Vlasyuk V.; Spiridonova O. (2013)

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. ...
IGR J16547-1916/1RXS J165443.5-191620-a new intermediate polar from the INTEGRAL galactic survey

Lutovinov A.; Burenin R.; Revnivtsev M.; Suleimanov V.; Tkachenko A. (2010)

We present the results of our optical identification of the X-ray source IGR J16547-1916 detected by the INTEGRAL observatory during a deep all-sky survey. Analysis of the spectroscopic data from the SWIFT and INTEGRAL ...
Influence of rotation velocity gradient on line profiles of accretion discs of CVs

Korčáková D.; Nagel T.; Werner K.; Suleimanov V.; Votruba V. (2011)

We show the influence of the Keplerian velocity shear on the line profiles of cataclysmic variable discs. The complete disc structure is taken into account. The radial disc structure follows the alpha disc approximation. ...
Investigation of the new cataclysmic variable 1RXS J180834.7+101041

Yakin D.; Suleimanov V.; Borisov N.; Shimanskii V.; Bikmaev I. (2011)

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 ...
