Mt. Suhora Survey - Searching for Pulsating M Dwarfs. I
We present the first results of our M dwarf survey in search for stellarpulsation in low mass main sequence stars. Theoretical calculationspredict that ? mechanism might drive a fundamental radial modein these stars and therefore pulsations could be observedphotometrically. Although M dwarfs are known for their flare and spotactivity they have not yet been the subject of dedicated time-seriessurveys for pulsation. In this work we include the light curves andamplitude spectra of 46 M dwarfs, which have been observed during thefirst two years of our survey. We did not detect any pulsations yet. Asa by-product of our search, we describe the light curves of some flare Mdwarfs. The survey will last for two more years and during that periodmore than a hundred of M0-M4 type main sequence stars will be observed.
