Abstract

A sample of the Large Sky Area Multi-Object Fibre Spectroscopic Telescope spectra of early-type M0-M3 dwarfs is compared with Kepler observations. It is found that M dwarfs with strong chromospheric emission in have large flare activity in general. The rotational periods derived from the Kepler measurements have close correlations with the sizes of the flares, the power-law distribution index, and the equivalent widths of the Hα emission. A clear trend exists for higher magnetic activities being detected in faster-rotating M dwarfs (rotation periods < 20 days).
