Journal ArticleDOI
New constraints on the chemical evolution of the solar neighbourhood and Galactic disc(s). Improved astrophysical parameters for the Geneva-Copenhagen Survey
Luca Casagrande,Ralph Schoenrich,Martin Asplund,Santi Cassisi,Ivan Ramirez,Jorge Melendez,Thomas Bensby,Sofia Feltzing +7 more
TL;DR: In this paper, the Geneva-Copenhagen survey was used to estimate stellar effective temperatures and metallicity scales for a Bayesian analysis of stellar ages, which is used for a better match to theoretical isochrones, which can provide better constraints on the physical processes relevant in the build-up of the Milky Way disc.

New constraints on the chemical evolution of the solar neighbourhood and galactic disc(s) - improved astrophysical parameters for the Geneva-Copenhagen Survey
Luca Casagrande,Ralph Schönrich,Martin Asplund,Santi Cassisi,I. Ramirez,Jorge Melendez,Thomas Bensby,Sofia Feltzing +7 more
TL;DR: In this article, the Geneva-Copenhagen survey was used for a re-analysis of the spectral properties of the stars in the solar neighborhood and the results showed that the stars are on average 100 K hotter and 0.1 dex more metal rich, which shifted the peak of the metallicity distribution function around the solar value.
Journal ArticleDOI
An absolutely calibrated T eff scale from the infrared flux method. Dwarfs and subgiants
TL;DR: In this paper, a large set of solar twins, stars which are spectroscopically and photometrically identical to the Sun, were used to set the absolute zero point of the effective temperature scale to within few degrees.

TL;DR: In this article, a catalogue of accurate stellar parameters for 451 stars that represent the HARPS Guaranteed Time Observations (GTO) "high precision" sample was presented, and a useful calibration for the effective temperature as a function of the index color B -V and [Fe/H was presented.
