Stellar evolution models are known to under-predict the radii of low-mass stars by between 5% and 10%, and there are a number of theoretical explanations for this discrepancy including metallicity and age variations, and magnetic suppression of convection. An eclipsing binary system in the Kepler field has been reported to have stars with masses of 0.68 and 0.34 solar and radii of 0.61 and 0.90 solar, respectively. We investigate this system with a new code under development that uses a Gaussian process technique to account for the out of eclipse light variations. We combine new NIR light curve data with the Kepler data and literature RVs to assess the feasibility that this system contains a hugely inflated M dwarf, or if another explanation of the data is preferred.
