GALEV（GALLEV EVolution）演化合成模型描述了从大爆炸后不久星星形成开始到今天，在≥13 Gyr的宇宙学时间尺度上，一般恒星种群、星星团和星系的演化，包括分辨的恒星种群和积分的光性质。对于星系，GALEV包括气体的化学演化和恒星内容的光谱演化的同时处理，允许我们称之为化学一致的处理：我们使用输入物理（恒星演化轨道，恒星产率和模型大气）为大范围的金属丰度和一致的帐户连续恒星世代的初始丰度增加。在这里，我们提出了最新版本的GALEV进化合成模型，现在可以在http://www.galev.org上交互式地使用。我们回顾了目前使用的输入物理，并详细介绍了如何在实践中实现这种物理。我们解释了如何使用交互式的Web界面来生成用户定义的参数模型，并给出了一系列的应用程序，可以使用GALEV进行研究，从星星集群，不受干扰的星系的各种类型的E-Sd的星暴和矮星系，无论是在本地和高红移宇宙。
GALEV (GALaxy EVolution) evolutionary synthesis models describe the evolution of stellar populations in general, of star clusters as well as of galaxies, both in terms of resolved stellar populations and of integrated light properties over cosmological time-scales of ≥13 Gyr from the onset of star formation shortly after the big bang until today. For galaxies, GALEV includes a simultaneous treatment of the chemical evolution of the gas and the spectral evolution of the stellar content, allowing for what we call a chemically consistent treatment: we use input physics (stellar evolutionary tracks, stellar yields and model atmospheres) for a large range of metallicities and consistently account for the increasing initial abundances of successive stellar generations. Here we present the latest version of the GALEV evolutionary synthesis models that are now interactively available at http://www.galev.org. We review the currently used input physics, and also give details on how this physics is implemented in practice. We explain how to use the interactive web interface to generate models for user-defined parameters and also give a range of applications that can be studied using GALEV, ranging from star clusters, undisturbed galaxies of various types E–Sd to starburst and dwarf galaxies, both in the local and the high-redshift Universe.
