SUMMARY:Multi-wavelength observations of High Mass X-Ray Binary Systems 
DESCRIPTION:Multi-wavelength observations of High Mass X-Ray Binary Systems
  \nDr. Pere Blay\n\nHigh Mas X-ray Binary Systems are important sources of
  information for  many astrophysical fields of research. They are composed
  by a compact  object (black hole or neutron star) and an early type star 
 (usually  known as the optical companion). Mass transfer from the later on
 to the  compact companion ends up as very bright emission of high energy  
 photons.  The multi-wavelength approach becomes mandatory in order to  und
 erstand these systems: a) Optical and IR bands are used to  characterize t
 he optical companion, b) Mass transfer and the local  ambient matter in th
 ese systems can be traced in UV and IR bands, c) The  behavior and propert
 ies of the compact companion can be inferred from  X-rays/gamma-rays obser
 vations, etc. We will review how this approach  helps to understand the be
 havior of several peculiar systems, including  the discovery of optical co
 unterparts, the estimation of compact object  masses, the characterization
  of the ambient matter (local extinction),  etc.
