Abstract (from CDS):
We have recently discovered periodic transient hard X-ray emission from a source, GRO 1849-03, possibly located in the 5kpc arm of the galaxy, using archival BATSE data. The source produces hard X-ray outbursts at regular 241-day intervals. Each outburst lasts roughly 13-days, reaching a peak luminosity of 75mCrab. The spectrum extends to at least 100keV with a photon power law index of -2.8. We interpret the emission as due to close encounters between a compact object and a companion star in a binary system.
