Next: Supernova Explosions Up: No Title Previous: X-ray Luminosity Evolution . The origin of cosmic rays (CR) (especially of very high energies, > eV) until now has been one of the unsolved problems in modern astrophysics. It is unclear as yet whether one universal mechanism of relativistic particle formation in our Galaxy operates or not, and if there are several different mechanisms, what is their relative contribution to CR formation. ... compact X-ray stars in binary systems. ...
