Much of our understanding of stellar astronomy rests upon the nearest stars. As individual objects they are the brightest and hence best studied examples of their spectral type. The solar neighbourhood sample also provides deep insight into the nature of our Galaxy's components, through studies of its stellar luminosity and mass functions, its kinematics, chemical composition, and multiplicity statistics.
We present the results and perspectives of a large program on the M dwarfs of the solar neighbourhood, dedicated to constrain the stellar physics and the formation of very low mass stars. Using adaptive optics images, infrared interferometry and accurate radial velocities, we have obtained multiplicity statistics of M dwarfs (binary fraction, period and mass ration distribution) and very low mass stars mass fuction, which are crucial constraints for stellar formation scenarii. We also present very accurate mass-metallicity-luminosity, and compare them to the prediction of recent stellar structure models.
