Characterizing epochs of star formation across the Milky Way disc using age-metallicity distributions of GALAH stars
Christian L. Sahlholdt, Sofia Feltzing, Diane K. Feuillet
We provide a detailed map of the ages and metallicities of turnoff stars in the Milky Way disc based on data from GALAH DR3 and Gaia EDR3. From this map, we identify previously und…
The BAyesian STellar Algorithm (BASTA): a fitting tool for stellar studies, asteroseismology, exoplanets, and Galactic archaeology
V. Aguirre Børsen-Koch, J. L. Rørsted, A. B. Justesen +16
We introduce the public version of the BAyesian STellar Algorithm (BASTA), an open-source code written in {\tt Python} to determine stellar properties based on a set of astrophysic…
Selecting accreted populations: metallicity, elemental abundances, and ages of the Gaia-Sausage-Enceladus and Sequoia populations
Diane K. Feuillet, Christian L. Sahlholdt, Sofia Feltzing +1
Identifying stars found in the Milky Way as having formed in situ or accreted can be a complex and uncertain undertaking. We use Gaia kinematics and APOGEE elemental abundances to…
Estimating the age-metallicity distribution of a stellar sample from the probability distributions of the individual stars
Christian L. Sahlholdt, Lennart Lindegren
Estimating age distributions, or star formation histories, of stellar populations in the Milky Way is important in order to study the evolution of trends in elemental abundances an…
