New constraints on the chemical evolution of the solar neighbourhood and Galactic disc(s)
New constraints on the chemical evolution of the solar neighbourhood and Galactic disc(s)
We present a re-analysis of the Geneva-Copenhagen survey, which benefits from the infrared flux method to improve the accuracy of the derived stellar effective temperatures and uses the latter to build a consistent and improved metallicity scale. Metallicities are calibrated on high-resolution spectroscopy and checked against four open clusters and …
