GALEX high time-resolution ultraviolet observations of dMe flare events

Aims.We present near ultraviolet (NUV: 1750–2800 Å) and far ultraviolet (FUV: 1350–1750 Å) light-curves for flares on 4 nearby dMe-type stars (GJ 3685A, CR Dra, AF Psc and SDSS J084425.9+513830.5) observed with the $\it GALEX$ satellite. Methods.Taking advantage of the time-tagged events recorded wi...
