Evidence of high redshift Galactic alpha-poor disc

The presence of [alpha/Fe]-[Fe/H] bi-modality in the Milky Way disc has animated the Galactic archaeology community since more than two decades. Our goal is to investigate the...二十余年来，银河系盘存在[α元素丰度比（alpha/Fe）]-[金属丰度（Fe/H）]双峰分布的现象，始终牵动着银河考古学界的研究热情。本研究旨在探讨……
