The contact binary GSC 04778-00152 with a visual companion
T. Tuvikene, T. Eenmäe, C. Sterken +1
Photometric and spectroscopic observations of the unstudied 12th-magnitude eclipsing binary GSC 04778-00152 are presented. We report the discovery of a visual companion about 1 mag…
Photometric study of selected cataclysmic variables
C. Papadaki, H. M. J. Boffin, C. Sterken +5
We present time-resolved photometry of five relatively poorly-studied cataclysmic variables: V1193 Ori, LQ Peg, LD 317, V795 Her, and MCT 2347-3144. The observations were made usin…
Spectroscopy of HD 77581 and the mass of Vela X-1
M. H. van Kerkwijk, J. van Paradijs, E. J. Zuiderwijk +3
We present new high-resolution, high signal-to-noise optical spectra of HD 77581, the optical counterpart of the X-ray source Vela X-1, and determine radial velocities from these s…
