Title: Measuring K Giant Star Fundamental Parameters Using the CHARA Array

Abstract: We plan to measure the angular diameters of three K giant stars in order to directly determine their linear radii and effective temperatures. This will be the crucial first step on the way to obtaining these single stars' masses directly, once the planned stellar oscillation measurements are obtained by Co-I Marie Hrudkovu. The combination of radii and masses will help to better calibrate stellar evolutionary models by direct mass determinations and significantly reducing the errors on radii estimates using other techniques.
