MAXI J1659-152: the shortest period black-hole binary?
Abstract
Observations of MAXI J1659-152 (Negoro et al. 2010, ATel #2873; Mangano et al. 2010, GCN #11296) with XMM-Newton on 27 and 28 September (Kuulkers et al. 2010, ATel #2887) clearly reveal variations in the light-curve similar to that reported from Swift/XRT observations (Kennea et al. 2010, ATel #2877). The dipping episodes as seen in the preliminary released data from the XMM/EPIC-pn (0.15-15 keV) and XMM/RGS (0.3-2 keV) instruments recur approximately every 2.4-2.5 hours, and show irregular structure which lasts between about 5 and 40 min.
