CaII spectroscopy of SMC red giants

We have obtained near-infrared spectra covering the CaII triplet lines for a large number of stars associated with 16 Small Magellanic Cloud (SMC) clusters using the VLT +...

本研究利用甚大望远镜（Very Large Telescope, VLT）+……获取了与16个小麦哲伦星系（Small Magellanic Cloud, SMC）星团相关的大量恒星的近红外光谱（near-infrared spectra），该光谱覆盖钙II三线系（CaII triplet lines）。
