CS isotopes towards Galactic centre clouds

Measuring isotopic ratios is a sensitive technique to obtain information on stellar nucleosynthesis and chemical evolution. We present measurements of the carbon and sulphur...同位素比值（isotopic ratios）测量是一种可用于获取恒星核合成（stellar nucleosynthesis）与化学演化（chemical evolution）相关信息的高灵敏分析技术。本研究展示了碳与硫的相关测量结果……
