Monitoring of Be X-ray binaries in the SMC

The Small Magellanic Cloud (SMC) hosts an extraordinary high number of nearlyone hundred known highmass Xray binaries (HMXBs), 63 with known Xraypulsations, indicating the spin of the neutron star (NS). Since most Be/Xraybinaries show strong Xray outbursts, they were detected rather incidentally byimaging Xray instruments and the evolution of their highenergy emission duringoutburst is still not known well. Within the field of view (FoV) of XMMNewtonup to 14 known BeXRB pulsars in the SMC can be observed simultaneously. Wepropose a monitoring with 14 observations over 52 days of a region with highdensity of HMXBs in the SMC, to study the evolution of the Xray spectrum andthe pulse profiles during outbursts with time and luminosity. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
