This emission was previously observed in M$\\;$dwarfs with planetary systems. However, low signal-to-noise prevented a conclusive determination of its origin. Possible sources include exoplanetary atmospheres, circumstellar gas disks, and the stellar surface. We use observations from the \"Measurements of the Ultraviolet Spectral Characteristics of Low-mass Exoplanet Host Stars\" (MUSCLES) Treasury Survey to study H$_2$ fluorescence in M$\\;$dwarfs.
