Abstract

We have studied multiwavelength photon emission from microquasars based on the framework of a leptonic jet model. In this model, non-thermal photons are produced by synchrotron, relativistic Bremsstrahlung, and angular dependent inverse Compton processes; they suffer a periodic orbital modulation due to the effects of different accretion rates and a variation of the soft photon density at different orbital phases as well as the orbital-phase and angular dependence |$\gamma$||$\gamma$| absorption and IC scattering. We applied this model to two possible microquasars, LS 5039 and LS I |$+$|61 303, and our results can roughly reproduce their observed spectral properties and the variability of these sources.
