Title: Stellar Radii of M-dwarfs

Abstract: Due to their high frequency within the Milky Way and in particular due to their low masses M-dwarfs have become of particular interest in the context of the search for extrasolar planets by the means of Doppler spectroscopy. With the current available instruments discoveries of rocky planets in habitable zones around M-dwarfs have become feasible. As uncertainties in the knowledge of the host stars are directly projected onto the determined properties of their companions, full characterizations of the science objects become essential. Unfortunately this is complicated for M-dwarfs, as it has been shown that empirical relations tend to become inaccurate with decreasing masses. Therefore direct measurements of stellar radii in this low-mass regime are supposed to further refine current relations and can serve as calibrators when characterizing samples in a homogenous way.
