Gamma-rays from the massive binary LSI 61°+303

摘要

We investigate the model for gamma-ray emission from massive binary LSI 61~(deg)+303 in which a young Vela type pulsar injects relativistic e~(+-)pairs into the radiation field of a massive Be type star.The gamma-rays are produced by e+-pairs in the inverse Compton scattering(ICS)occurring in the pulsar wind zone confined by the shock formated in the collisions of the stellar and pulsar winds.We calculate these gamma-ray spectra as a function of the phase of the pulsar on its eccentric orbit around the massive star.
