Descripción
Using data obtained during the RATS-Kepler project, we identified one
short-duration flare in a 1 h sequence of ground-based photometry of the
dwarf star KIC 5474065. Observations made using Gran Telescopio Canarias
show that it is a star with an M4V spectral type. Kepler observations
made using 1 min sampling show that KIC 5474065 exhibits large-amplitude
(δF/F > 0.4) optical flares which have a duration as short as
10 min. We compare the energy distribution of flares from KIC 5474065
with that of KIC 9726699, which has also been observed using 1-min
sampling, and ground-based observations of other M dwarf stars in the
literature. We discuss the possible implications these short-duration,
relatively low-energy flares would have on the atmosphere of exoplanets
orbiting in the habitable zone of these flare stars.

La espectroscopía de estrellas nos permite determinar las propiedades y composiciones químicas de las mismas. A partir de esta información para estrellas de diferente edad en la Vía Láctea es posible reconstruir la evolución química de la Galaxia, así como el origen de los elementos más pesados que el boro, forjados principalmente en los interiores
