共生星云和行星状星云光度函数的比较

Comparing Symbiotic Nebulae and Planetary Nebulae Luminosity Functions

Adam Frankowski, Noam Soker

摘要:

我们将观测到的[O III] 5007 A线上的共生星云(SyN)光度函数(SyNLF)与行星状星云(PN)光度函数(PNLF)进行了比较,发现在0.5- 0.8等的不确定度范围内,银河系SyN的内禀SyNLF(ISyNLF)具有与PNLF非常相似的截止光度和一般形状。SyN和PN的[O III]/(H α +[N II])线比也显示出相关性。这些结果的普遍性的PNLF的可能影响进行了简要概述。

英文摘要:

We compare the observed symbiotic nebulae (SyN) luminosity function (SyNLF) in the [O III] 5007A line to the planetary nebulae (PN) luminosity function (PNLF) and find that the intrinsic SyNLF (ISyNLF) of galactic SyNs has - within its uncertainty of 0.5-0.8mag - very similar cutoff luminosity and general shape to those of the PNLF. The [O III]/(Halpha+[N II]) line ratios of SyNs and PNs are shown to be also related. Possible implications of these results for the universality of the PNLF are briefly outlined.
