Mt. Suhora survey - Searching for pulsating m dwarfs. Ill
We present our final report on the search for pulsating M dwarfs. We used moderate ( < 1 m) ground-based telescopes. Our detection was limited to 1 ppt, which is roughly 0.1 % of flux variation. We employed both the Fourier technique and Phase Dispersion Minimization (PDM) method. Our data analyses revealed no detection of pulsations in M dwarfs down to the above amplitude level. The results of our survey cannot reject or confirm the theoretical calculations suggesting the M dwarfs can pulsate, however, if the pulsations exist in these stars their amplitudes must be lower than 1 ppt. As a by-product of our search we found several new variable stars, including pulsating stars, binary systems and flare stars.
