[74.04U] Basic Physical Parameters of Nearby G and K Giants and Subgiants

P.E. Robinson, R.O. Gray (Appalachian State University)

As part of the Nearby Stars (NStars) Program at Appalachian State University, we are determining the basic physical parameters of G and K giants and subgiants within 40 parsecs of the Sun ( \approx 170 stars). Stellar radii are being determined using the Infrared Flux Method (IRFM, Blackwell & Lynas-Gray, 1994). Combining the radii with luminosity and parallax data, we are determining the effective temperatures; surface gravity is determined by combining the calculated radii with mass estimates from evolutionary models. Metallicities [M/H] are then determined using the simplex method of Gray et al. (2001).
