Radial velocities of Berkeley 32 stars

Measurements of lithium (Li) abundances in open clusters provide a unique tool for following the evolution of this element with age, metallicity, and stellar mass. In spite of...对疏散星团（open clusters）中锂（Lithium, Li）丰度的测定，为探究该元素随年龄、金属丰度（metallicity）及恒星质量（stellar mass）的演化规律提供了独一无二的研究工具。尽管……
