Discovery of flare activity on the very low luminosity red dwarf G 51-15. (original) (raw)

Abstract
Flare activity has been discovered on G 51-15, the intrinsically second faintest star known, and the faintest one with hydrogen Balmer lines in emission. A comparison of the two faintest stars known with other flare stars indicates that they are considerably less flare active than CN Leo or UV Cet. A possible explanation may be that a star's age is important to its flaring rate, but this is difficult to quantify from existing data on low luminosity dwarfs.
