BACCHUS: Brussels Automatic Stellar Parameter
T. Masseron · Dépôt institutionnel de l'Université libre de Bruxelles (Université Libre de Bruxelles) · 2016
The BACCHUS (Brussels Automatic Stellar Parameter) pipeline derives the broadening parameters, metallicity, and chemical abundances of stars. The code has three different modules that derive equivalent widths, stellar parameters, and abundances and takes advantage of asteroseismic data by fixing log g throughout the analysis process to those determined by Pinsonneault et al. (2014). The Teff is also fixed and is selected to corrected ASPCAP Teff from DR10 to be consistent with the asterosismic log g values. BACCHUS requires the radiative transfer code Turbospectrum (ascl:1205.004) and the MARCS model atmosphere grid.
