dc.description In the last two decades, astrophysicists have discovered one of the most important phenomena in the outer space: the existence of gamma-ray binary systems. Unlike the other binaries, these ones emit photons in high energy or very high energy. These are composed of a compact object and a massive star, which interaction causes the gamma-ray ux emission, that is known to be modulated by the orbital period of the system. Here, this orbital period is going to be our aim of study. Using data obtained by H.E.S.S. (High Energy Stereoscopic System), we are going to determine a periodicity that is coincident with the orbital period of the gamma-ray binary system LS 5039 using the Phase Dispersion Minimization (PDM) technique. With a programming language, we are going to implement a code to perform PDM with a trial of periods to, finally, get the real one
