Cygnus X-3

Cygnus X -3 ( V1521 Cygni ) is a rare example of an X-ray binary star system, such as the Hercules X - 1 in the VHE gamma-ray range (abbr. VHE for engl. Very high energy ) sends out periodic radiation. He is one of the brightest X-ray sources in our galaxy. The binary star system consists of a massive neutron star or a black hole and a classified by observations in the infrared as a Wolf- Rayet star companion. Recent observations in higher energy ranges can neither a steady nor a pulsed emission of Cygnus X-3 demonstrate. Are examined data from the HEGRA IACT measurements from 2001 to steady and periodic emission towards.
