Abstract: We study the high energy emission from the Be-pulsar system B1259–63/SS 2883, based on the result from a Smoothed Particle Hydrodynamics (SPH) simulation. As a first step toward the understanding of this complicated system, the simulation takes into account only the tidal effect of the pulsar on the circumstellar disk of the Be star. Using the simulation data, we estimate the position where the ram pressure of pulsar wind is balanced with the gas pressure of the Be-star circumstellar disk. We assume that the shock waves are generated in this region, where the particle acceleration takes place. We calculate the synchrotron spectrum by the accelerated electrons and magnetic field of the pulsar. We also calculate the inverse Compton spectrum of soft photons from the Be star and background radiations. The resulting fluxes in X-ray and gamma-ray bands show asymmetric double-peaked light curves similar to the observed ones.
