RX J1643.7+3402 : a new bright cataclysmic variable
A. M. Mickaelian, S. K. Balayan, S. A. Ilovaisky +3
We report the discovery of a new bright (V12.6) cataclysmic variable star identified with the ROSAT X-ray source RX J1643.7+3402. Spectroscopic and photometric observations s…
Hipparcos results on massive X-ray binaries
Claude Chevalier, Sergio A. Ilovaisky
We present results on parallaxes, magnitudes and proper motions for 17 optically identified massive X-ray binaries (MXRB) which were observed during the Hipparcos astrometry missio…
The ROSAT Bright Source RX~J0222.4+4729: an Active Nearby Short-period Binary of the BY Dra type
Claude Chevalier, Sergio A. Ilovaisky
We report the discovery of a new BY Dra-type binary identified as the optical counterpart of the bright source RX J0222.4+4729 detected during the ROSAT All-Sky Survey (Voges et al…
The quiescent light curve and orbital period of GRO~J0422+32
Claude Chevalier, Sergio A. Ilovaisky
CCD photometry of the black hole candidate GRO~J0422+32 in quiescence, obtained at Haute-Provence from 1994 November to 1995 February, reveals a double-wave modulation at a period…
