论文摘要
我们回顾了当前在星系中使用硫作为全局金属性示踪剂的方法,该方法允许使用主要的红色到近红外光谱区域进行完整的丰度分析,并扩展了直接得出的丰度的范围,最大5倍S Solar Photoarphopheric值。还回顾了通过S23参数对硫的经验校准。
We review the present methodology for the use of Sulfur as global metallicity tracer in galaxies, which allows performing a complete abundance analysis using mainly the red to near infrared spectral region, and extending the range of directly derived abundances up to 5 times the S solar photospheric value. The empirical calibration of Sulfur via the S23 parameter is also reviewed.
