摘要：

LS I +61 303 has been recently detected as a periodic gamma-ray source by the Major Atmospheric Imaging Cerenkov (MAGIC) telescope. A distinctive orbital correlation of the gamma-ray emission was found. This work shows that the range of uncertainties yet at hand in the orbital elements of the binary system LS I +61 303 as well as in the possible assumptions on the stellar wind of the optical companion play a non-negligible role in the computation of opacities to high-energy processes leading to gamma-ray predictions. The geometry influence on the propagation and escape of gamma-ray photons is explored. With this study at hand, we analyze the results of a pulsar wind zone model for the production of gamma-rays and compare it with recent MAGIC observations.
