We present time-resolved spectroscopy and photometry of a new long-period cataclysmic variable (CV) identified from a combined X-ray (ROSAT) /infrared (2MASS) selection method, 1RXS J0629-0335. The preliminary orbital period of ˜9 h has been estimated from its radial velocity variation. We obtained photometry of 1RXS J0629-0335 throughout one month, revealing long-term variability and suggesting that the system has frequent dwarf nova outbursts.

Binary Stars
The study of binary stars is essential to stellar astrophysics. A large number of stars form and evolve within binary systems. Therefore, their study is fundamental to understand stellar and galactic evolution. Particularly relevant is that binary systems are still the best source of precise stellar mass and radius measurements. Research lines
