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…
The HR 1614 moving group is not a dissolving cluster
Iryna Kushniruk, Thomas Bensby, Sofia Feltzing +3
The HR 1614 overdensity in velocity space and has for a long time been known as an old (~2 Gyr) and metal-rich ([Fe/H]~0.2) nearby moving group that has a dissolving cluster origin…
The GALAH survey: Multiple stars and our Galaxy. I. A comprehensive method for deriving properties of FGK binary stars
G. Traven, S. Feltzing, T. Merle +24
Binary stellar systems form a large fraction of the Galaxy's stars. They are useful as laboratories for studying the physical processes taking place within stars, and must be corre…
The SkyMapper-Gaia RVS view of the Gaia-Enceladus-Sausage -- an investigation of the metallicity and mass of the Milky Way's last major merger
Diane K Feuillet, Sofia Feltzing, Christian Sahlholdt +1
We characterize the Gaia-Enceladus-Sausage kinematic structure recently discovered in the Galactic halo using photometric metallicities from the SkyMapper survey, and kinematics fr…
Characteristics of the two sequences seen in the high-velocity Hertzsprung-Russell diagram in Gaia DR2
Christian L. Sahlholdt, Luca Casagrande, Sofia Feltzing
In this study we use a sample of about 9 million SkyMapper stars with metallicities to investigate the properties of the two stellar populations seen in the high-velocity ($V_{\rm…
