The most accurate direct measurements of fundamental stellar properties are from eclipsing binary (EB) stars. Eclipsing binaries are thus central to calibrating stellar evolution models and defining empirical relationships which are used in many areas of research. However, one of the most compelling problems to arise in the last few years is the reported discrepancy between the observed and theoretically predicted radii and temperatures of M dwarf stars. This problem manifests itself in many different objects and kinds of analyses including short period EBs, interferometric radius measurements, active field M dwarfs, and more recently in one very long period M dwarf EB. Furthermore, the discrepancy is observed over a range of masses from K-dwarfs down to the bottom of the main sequence. In order to explore this problem, we have an ongoing program to examine the mass-radius relation of M dwarfs as a function of metallicity and activity using a large sample of EBs composed of an F, G or K dwarf primary star and an M dwarf secondary. Here, I describe our project and give some preliminary results.
