PolStar - An Explorer-Class FUV Spectropolarimetry Mission to Map the Environments of Massive Stars

Abstract

International audiencePolStar is an Explorer-class far ultraviolet (FUV) spectropolarimetry mission designed to target massive stars and their environments. PolStar will take advantage of resonance lines only available in the FUV to measure for the first time the magnetic and wind environment around massive stars to constrain models of rotation and mass loss
