Discovery of flare activity on the dwarf M stars, GI 375 and GI 431

  • 1. Armagh Observatory, (Ireland)

Description

Optical and infrared photometry plus spectroscopic data is present for two new flare stars, GI 375 and GI 431. Both of these stars have the hydrogen Balmer lines strongly in emission. Several flares were detected on GI 375 implying a high level of flare activity. The Hα surface flux of 1.0 x 106 erg cm-2s-1 for both stars is similar to that of other active flare stars. Fluxes are given for several of the higher Balmer lines
