The 1st massive binary star, epsilon Lupi, in which both stars have magnetic fields has been discovered by a PhD candidate. A binary star is a star system consisting of 2 or more stars, orbiting around their common center of mass.For the past few years, BinaMIcS (Binarity and Magnetic Interactions in various classes of Stars) collaboration, formed to study the magnetic properties of close binaries, has been trying to find such an object. They have now discovered one using the Canada-France-Hawaii Telescope.
