TL;DR
This paper analyzes over three decades of observations of Cygnus X-3, revealing its gamma-ray emission properties and proposing a model for this unique binary system with a relativistic object and a massive star.
Contribution
It provides a comprehensive model of Cygnus X-3 based on long-term gamma-ray observations, highlighting its variable high-energy radiation source.
Findings
Gamma-ray emission from tens of MeV to thousands of TeV
Correlation between gamma-ray activity and binary orbit
Identification of variable high-energy radiation source
Abstract
Long observation (1972 - 2009) of the powerful discrete source in Galaxy Cygnus X-3 discovered its main properties and let to develop a real model of this unique object. It is short binary system with 4.8 hour orbital period including relativistic object (neutron star or black hole) and massive star. Source most activity is seen in gamma-rays from tens MeV to thousands TeV.
