Follow-up of X-ray binary candidates in eRosita survey.

The ongoing eRosita survey (eRASS) is expected to discover several millions ofnew Xray sources and double the number of known Galactic Xray binaries (XRBs).This will help to clarify several longstanding questions related to theaccretion physics in lowluminosity XRB, their numbers, origin, and evolution.To fully realise this potential, followup observations in Xray and other bandsare, however, essential. Here we propose to start the exploration of this newexciting dataset with XMMNewton and followup several new High mass Xraybinary (HMXB) candidates identified with Rosita in order to confirm preliminaryidentification and study their Xray properties in detail. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
