Descripción
High-resolution spectra of a sample of all known stars more luminous
than MV=+6.5 and closer than 15 parsecs are being analyzed
spectroscopically in order to derive their effective temperatures and
surface gravities. These spectra are taken from the database of "A
Spectroscopic Survey of Stars in the Solar Neighborhood". The analysis
utilizes a sample of Fe I and Fe II lines. The stellar parameters
derived from this analysis are compared to previously published values
from various studies. A comparison of the different temperature scales
will be discussed as well as the impact these differences have on
chemical abundance studies of cool stars. This research is supported in
part by the National Science Foundation (AST03-07534 and
AST03-07532),NASA (NAG5-13175), and JPL.
