Isochrones of M67 with an Expanded Set of Parameters
Lucas Viani (Yale University), Dr. Sarbani Basu (Yale University)

We create isochrones of M67 using YREC (The Yale Rotating Stellar Evolution Code). In addition to metallicity, parameters that are traditionally held fixed, such as the mixing length parameter and initial helium abundance, also vary. The amount of convective overshoot is also changed in different sets of isochrones. Models are constructed both with and without diffusion. We examine limits on the age and distance to the cluster obtained by this wider set of isochrones.
