HII regions in dwarf irregular galaxies

We present long-slit optical spectroscopy of 67 HII regions in 21 dwarf irregular galaxies to investigate the enrichment of oxygen, nitrogen, neon, sulfur, and argon in low-mass...本研究呈现了21个矮不规则星系（dwarf irregular galaxy）中67个H II区（H II region）的长缝光学光谱法（long-slit optical spectroscopy）观测数据，旨在探究低质量星系内氧、氮、氖、硫及氩的元素富集情况。
