Title: Eclipsing Binary M dwarfs and the Low Mass Stellar M/L Ratio
Abstract: We propose to complete our on-going survey with the KPNO-4m of a well selected sample of open clusters to identify candidate eclipsing M- dwarfs through their relative light variations. These clusters are of known distance, age, and metallicity from their higher luminosity turn- off members. The candidate eclipsing M-dwarfs will, with follow-up spectroscopy, be used to calibrate the Mass-Luminosity-Radius relation at low masses, as a function of age and metallicity. This is a fundamental, but poorly constrained quantity for low mass stars. Side benefits of our survey will include an improved knowledge of the binary fraction at low masses. Further, we will obtain a high-quality set of CMDs, as a function of location within a given cluster, to allow investigation of mass segregation and dynamical evolution within open clusters.
