Abstract: Gamma-ray binaries are systems composed of a massive star and a compact object that produce emission from radio to very high energy gamma-rays. LS I +61 303 is one of the only six gamma-ray binaries discovered so far. It is thought that gamma-ray binaries contain a young highly rotating neutron star as compact object, and the emission is produced by the interaction between its relativistic pulsar wind and the stellar wind, However, in the case of LS I +61 303 a microquasar scenario is still considered and results pointing to oppose directions have been published during the last decades. Here we provide a review about the state of the art of LS I +61 303, summarizing the observed emission from radio to very high energy gamma-rays along all these years, and we discuss the proposed scenarios that can explain such emission.<br />Comment: 9 pages to be published in the proceedings of XII Multifrequency Behaviour of High Energy Cosmic Sources Workshop, Palermo (Italy), PoS(MULTIF2017)045
