Description

Nine new X-ray sources were discovered by the Ginga satellite during survey observations near the Galactic bulge region. Seven of the sources were found to have a hardness ratio similar to that of low-mass binary X-ray sources (LMXBs). One source has a hard spectrum with large low-energy absorption similar to that of X-ray pulsars. The other source, GS 1734-275, was found to be variable over a long time. It also exhibited an unusually soft spectrum, and, hence, could be a potential candidate for a black-hole binary. We also found that the EXOSAT new source, GPS 1742-326, has a typical LMXB spectrum.
