INTEGRAL observations of GRO J1008-57 in outburst
Abstract
The Be X-ray binary GRO J1008-57 is known to display regular outburts, with a period of 248 days (ATel #940; Coe et al. 2007, MNRAS 378, 1427). In the past, it has been detected by INTEGRAL at a level of 30 mCrab in October 2005 (ATel #647; in the 18-45 keV energy range), but also in June 2004 (Coe et al. 2007). Swift/BAT detected a brighter than usual flare in November 2007 (ATel #1298), with a level of 100 mCrab up to 400 mCrab (in the 15-50 keV energy range; see <A href=http://heasarc.gsfc.nasa.gov/docs/swift/results/transients/GROJ1008-57/
