Superorbital variability of the gamma-ray binary LS I +61 303 studied with MAGIC

The gamma-ray binary LS I +61 303 has been detected from radio up to very high–energy gamma rays. Its emission is likely originated by the interaction of the stellar wind and a relativistic outflow. The broadband emission shows a periodicity of about 26.6 days, coincident with the orbital period. A...
