Investigating lower limit of metallicity for Galactic thin disk

Guozhen Hu, Zhengyi Shao, Erbil Gugercinoglu +1

We explore the metal-poor regime of the Galactic disk on the distribution of stars in the [$\alpha$/M]-$V_{\varphi }$ plane, to identify the most metal-poor thin disk (MPTnD) stars belonging to…
