18 Sco atomic data and equivalent widths

We study with unprecedented detail the chemical composition and stellar parameters of the solar twin 18 Sco in a strictly differential sense relative to the Sun. Our study is...本研究以前所未有的精细程度，针对太阳孪生星（solar twin）18 Sco，以太阳为参照开展严格差分分析，对其化学组成（chemical composition）与恒星参数（stellar parameters）展开研究。本研究……
