VARIABLE GALACTIC SOURCES DETECTED WITH HESS

The very high energy gamma-ray telescope HESS has surveyed most of the galactic volume revealing over 50 new TeV sources, the majority of which are extended^1,2. Of the small fraction of point-like sources, only two show variable emission; PSR B1259+63 and LS 5039. Both of these objects are associated with X-ray and radio emitting binary stellar systems. The unidentified point-like source HESS J0632+057 has been suggested as a new member of this rare class of objects.
