High - Energetic Galactic Objects

Theoretical work as well as observations of high energy phenomena in galactic objects concentrates on supernova remnants, pulsars, and on accreting X-ray binaries.

Accretion phenomena:

Accretion of matter onto a compact object is a common mechanism to generate the high energy output found in many galactic X-ray sources. Of particular interest is a class of objects called 'Galactic Micro Quasars' in which a substantial amount of the energy output is in form of matter outflow from the compact object. The prototype of these sources is SS433, a jet source at the center of the supernova remnant W50 which has been studied in X-rays for more than a decade.

Supernova remnants:

Supernova remnants are the endpoints of the stellar evolution and they provide a substantial part of the energy input to the interstellar medium. While in plerions like the Crab nebula one can study the interaction of the central pulsar with its surroundings, shell - like remnants like Tycho or Kepler provide a diagnostic tool for the energetics of the explosion as well as for the chemical composition of the progenitor star.
