On the origin of the chemical bimodality of disc stars: a tale of merger and migration
T Buck - Monthly Notices of the Royal Astronomical Society, 2020 - academic.oup.com
ABSTRACT The Milky Way's (MW) stellar disc exhibits a bimodality in the [Fe/H] versus
[α/Fe] plane, showing a distinct high-and low-α sequences whose origin is still under debate …
