Very Metal-poor Stars in the Solar Vicinity: Kinematics and Abundance Analysis

Abstract Very metal-poor stars contain crucial information on the Milky Way’s infancy. In our previous study we derived a mean age of ∼13.7 Gyr for sample these in Sun’s vicinity. this work, investigate chemical and kinematic properties with goal obtaining some insights into their origin parent population. We did not find any Al–Mg anticorrelation, which leads us to conclusion that form globular clusters, while detailed analysis orbital parameters reveals are most probably associated pristine bulge Way. then sketch scenario formation Way first structure was through rapid collapse. The other components have grown later on, significant contribution accreted structures.
