GeV LIGHT CURVES OF YOUNG SUPERNOVA REMNANTS
1Institute for Applied Problems in Mechanics and Mathematics,
Observational data from the Fermi Gamma-ray Space Telescope are analyzed with the goal in mind to look for variations in the \g-ray flux from young shell-like supernova remnants. A uniform methodological approach is adopted for all SNRs considered. G1.9+0.3 and Kepler SNRs have not been detected. The light curves of Cas A and Tycho SNRs are compatible with the steady GeV flux during the recent ten years, as also X-ray and radio fluxes. Less certain results on SN1006 and SN1987A are discussed.
Key words: supernova remnants, gamma-rays, light curves
