Very metal-poor stars in the solar vicinity: kinematics and abundance analysis

Anastasiia Plotnikova, Giovanni Carraro, Sandro Villanova +1

Very metal-poor stars contain crucial information on the Milky Way's infancy. In our previous study \citep{Plotnikova_2022} we derived a mean age of 13.7 Gyr for a sample of…
