摘要: Abstract PSR B1259-63/LS 2883 is a very high energy (VHE; E > 100 GeV ) γ -ray emitting binary consisting of 48 ms pulsar orbiting around Be star with period ∼ 3.4 years . The features circumstellar disk which inclined respect to the orbit in such way that crosses it twice every orbit. provides an additional field target photons may contribute inverse Compton scattering and γγ -absorption, leaving characteristic imprint observed spectrum emission. At energies, source was detected for first time during previous periastron passage took place on December 15, 2010. Fermi Large Area Telescope (LAT) reported spectacular unexpected flare occurring 30 days after lasting about 7 weeks. In this paper, we study signatures Compton-supported, VHE induced pair cascades disc their possible contribution flux. We show cascade emission generated cannot be responsible flare, but might explain close periastron. also -absorption TeV light curve.
