Speaker: Vladimir Usov (WIS) April 24, 2013 Colliding stellar winds in binaries of massive stars: theory and multi-wavelength observations
One
of the main properties of massive stars is a very intense, highly
supersonic outflow of gas. If massive stars belong to binary
systems, the stellar winds can collide and shock waves are formed. I
will discuss the hydrodynamics of stellar wind collision and physical
processes in colliding stellar winds, such as gas heating and
acceleration of particles in the shocks, formation of dust and
generation of X-ray, gamma-ray, radio and infrared emission. I
will review observational data on this emission.
