GALEV evolutionary synthesis models - I. Code, input physics and web-interface
摘要：
GALEV演化合成模型描述了一般的恒星星族、星团和星系的演化，包括从大爆炸后不久开始的恒星形成到今天，在大于13 Gyr的宇宙学时间尺度上分辨的恒星星族和综合光特性。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，并始终占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进化的合成模型，现在可以交互式地在www.galev.org。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网络界面来生成用户定义参数的模型，并给出了一系列可以使用GALEV进行研究的应用程序，从星团，各种类型的未受干扰的星系E.在本星系和高红移宇宙中，Sd到星暴和矮星系。
英文摘要：
GALEV 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 timescales 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 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.
