Optical microflares in LS I +61 303 and the search for their multiwavelength counterpart

Context. Stellar sources of gamma rays are one of the front lines in modern astrophysics whose understanding can benefit from observational tools not originally designed for their study. Aims. We take advantage of the high precision photometric capabilities of present-day space facilities to obtain...
