Detection of X-ray emission from the vicinity of two short-period RS CVn-like binaries

Two new soft X-ray sources H0118 + 067 and H0630 + 82 have been detected with a low energy detector of the HEAO A-2 experiment. Short-period RS CVn-like binaries UV Psc and SV Cam lie within the error boxes of these sources and are proposed as the optical identifications for the two X-ray sources. T...

Zusammenfassung:Two new soft X-ray sources H0118 + 067 and H0630 + 82 have been detected with a low energy detector of the HEAO A-2 experiment. Short-period RS CVn-like binaries UV Psc and SV Cam lie within the error boxes of these sources and are proposed as the optical identifications for the two X-ray sources. The light curve of HO118 + 067, identified with UV Psc, indicates an X-ray flare event which commenced on 1978 January 11.6 and persisted until at least January 12.7. It is suggested that H 0118 + 067 and the flaring X-ray source H 0123 + 075, detected by the medium and high energy detectors of the HEAO A-2 experiment, may be the same object. The observed X-ray luminosity of the sources are in the same range as observed for other RS CVn binaries. The X-ray emission is probably of coronal origin.
