    Under the assumption that LS 5039 is a system composed of a pulsar rotating around an O6.5 V star in a ∼3.9 day orbit, we present the results of a theoretical modeling of the high-energy phenomenology observed by the High Energy Stereoscopy Array (H.E.S.S.). This model (including a detailed account of the system geometry, Klein-Nishina inverse Compton scattering, γ-γ absorption, and cascading) is able to describe well the rich observed phenomenology found in the system at all timescales, both flux- and spectrum-wise. © 2007.
