Title: Calibrating Stellar Evolution Models and Defining the Radius-Activity and -Metallicity Relations for M dwarfs

Abstract: Our goal is to empirically determine the mass-radius relationship of M dwarfs using a sample of F/G/K+M dwarf eclipsing binaries (EBs) in order to establish in detail how the measured radii depend on activity and metallicity. In addition, we aim to make precise measurements of the temperatures and metallicities of known benchmark EBs which lack this information. This will allow for critical testing of theoretical stellar evolution models.
