Optical counterparts of ROSAT X-ray sources in two selected fields at low vs. high Galactic latitudes
J. Greiner, G. A. Richter
The optical identification of large number of X-ray sources such as those from the ROSAT All-Sky Survey is challenging with conventional spectroscopic follow-up observations. We in…

S 10947 Aql = RX J2009.8+1557: A probable RS CVn star which sometimes stops its eclipses
G. A. Richter, J. Greiner
We report the discovery of a new variable star, called S 10947 Aql, as the likely optical counterpart of RX J2009.8+1557. The optical variability pattern as well as the detected X-…

S 10943 Vulpeculae: A New ROSAT Selected Dwarf Nova, probably of SU Ursae Majoris Subclass
G. A. Richter, J. Greiner, P. Kroll
We have identified the ROSAT all-sky survey source RX J1953.1+2115 with a newly discovered dwarf novae (named S 10943 Vulpeculae) with a recurrence time of 83.6 days. With the expe…
