[91.09] Contributions to the NStars Program: Spectroscopy and Physical Parameters of the Solar-type Stars within 40 parsecs of the Sun

R.O. Gray (Appalachian State Univ.), C.J. Corbally (Vatican Obs.), R.F. Garrison (David Dunlap Obs.), M.T. McFadden (Appalachian State Univ.), A.A. O'Donoghue, E.R. Knox (St. Lawrence Univ.), C.E. McGahee, E.J. Bubar (Appalachian State Univ.)

During the past four years, Appalachian State University, the Vatican Observatory and the David Dunlap Observatory have been engaged in a Nearby Stars (NStars) project to obtain spectra of all dwarf and giant stars earlier than M0 within 40 parsecs of the Sun (3600 stars). We are using these spectra to provide new, precise spectral types and basic physical parameters (Teff, \log g and [M/H]). In addition, we are providing measures of the chromospheric activity of these stars. This poster will discuss the analysis of nearly the entire southern NStars sample. Included will be a discussion of the correlation of chromospheric activity with other physical parameters, the physical parameters of stars with exoplanets and the refinement of the stellar census within 40 parsecs of the Sun. This project was supported by a contract from NASA/JPL.
