模拟HII星系中的星暴:从化学到分光光度演化自洽模型

Modelling Starburst in HII galaxies: From chemical to spectro-photometric evolutionary self-consistent models

M. L. Martin-Manjon, M. Molla, A. I. Diaz, R. Terlevich

摘要:

我们已经计算了一系列现实的和自洽的模型,再现HII星系的属性。HII星系的发射光谱是通过光电离代码Cloudy再现的,使用模型HII星系的光谱能量分布作为电离光谱,该光谱是使用新的和更新的恒星星族合成模型计算的(PopStar,Molla等人08),这又是根据化学演化代码给出的恒星形成历史和金属丰度演化计算的。我们的技术再现了观测到的丰度,诊断图,颜色和等效宽度与本地HII星系的颜色关系

英文摘要:

We have computed a series of realistic and self-consistent models that reproduce the properties of HII galaxies. The emitted spectrum of HII galaxies is reproduced by means of the photoionization code CLOUDY, using as ionizing spectrum the spectral energy distribution of the modelled HII galaxy, calculated using new and updated stellar population synthesis model (PopStar, Molla et al. 08) This, in turn, is calculated according to a star formation history and a metallicity evolution given by a chemical evolution code. Our technique reproduces observed abundances, diagnostic diagrams, colours and equivalent width vs. colour relations for local HII galaxies
