资源简介:
We present a method for the determination of [{alpha}/Fe] ratios from low-resolution (R=2000) SDSS/SEGUE stellar spectra. By means of a star-by-star comparison with degraded...
本研究提出了一种基于分辨率R=2000的低分辨率斯隆数字巡天(Sloan Digital Sky Survey, SDSS)/斯隆银河探索扩展计划(Sloan Extension for Galactic Understanding and Exploration, SEGUE)恒星光谱,测定[α/Fe]丰度比的方法。本研究通过逐星比对降分辨率后的……
