近年来,星系外行星状星云(XPN)已成为研究星系外恒星群和化学演化的热点。在超巨星的旁边,它们为附近星系中单个恒星的光谱研究提供了独特的可能性——事实上,它们是用现代仪器研究中低质量恒星化学成分的唯一方法。虽然XPN在[O III] A5007发射线中相对容易检测到,但较弱的诊断线的分光光度法非常困难。我们将利用PMAS的独特功能,对M31中央kpc微弱背景受限的XPN进行有竞争力的分光光度测量。
英文摘要
Extragalactic Planetary Nebulae (XPN) have recently become of interest for studies of stellarpopulations and chemical evolution in external galaxies. Next to supergiant stars, they offera unique possibility for spectroscopic studies of individual stars in nearby galaxies — in factthey present the only way to look into the chemical composition of low-intermediate massstars with present day instrumentation. Although XPN are relatively easy to detect in the[O III] A5007 emission line, the spectrophotometry of the fainter diagnostic lines is extremelydifRcult. We will use the unique capabilities of PMAS for a competitive spectrophotometricsurvey of faint background-limited XPN in the central kpc of M31.
