Title: Homogeneous and Systematic Characterization of Bright Southern Stars in Support of the BRITE Nano-Satellites

Abstract: We propose to acquire an uniform set of high-resolution, high S/N optical spectra, using the \sc chiron spectrograph on the \sc ctio 1.5m telescope, for ~eq160 stars with V<4^th magnitude in the southern sky during semester 2013B. These spectra will be used to determine, in an homogeneous and systematic manner, fundamental stellar parameters for each object (\em e.g., RVs, V sini, T_eff, log g, [Fe/H], [Li/H] \em etc). Our proposal is part of a programmatic follow-up observing campaign of objects that are currently being observed by the two recently-launched \bf BRITE (BRight Target Explorer) nano-satellites, which will photometrically measure (to, at worst, 1-mmag precision) low-level oscillations and temperature variations for all stars with V<4, specifically concentrating on the most massive and luminous pulsators. The PI, and most co-Is, are all members of the \sc brite- Constellation International Advisory Science Team, and all applicants are members of the \sc brite Ground Based Observations Team. Dr. Weiss is a co-PI of the \sc brite-Constellation project, and is also on its Executive Committee.
