用于星震学的恒星演化模型网格(CESAM + POSC)
Grids of stellar evolution models for asteroseismology (CESAM + POSC)
摘要:
在本文中,我们提出了一个网格的恒星演化模型,计算与最新的物理描述的内部结构,使用代码d '恒星演化自适应等模块(CESAM)。演化序列的跨度从前主序星到红巨星分支的开始,覆盖了低质量和中等质量恒星的典型质量间隔。化学成分(氦和金属丰度)是太阳的。振荡的频率,计算特定的恒星模型的网格使用波尔图振荡代码(POSC),也提供。完成这项工作是为了支持在演变和地震工具活动(CoRoT/ESTA)内准备CoRoT任务。另一方面,更一般地说,网格也可以用来解释单个恒星或恒星星族的观测性质。网格(数据和文档)可在http://www.astro.up.pt/corot/models/cesam上找到
英文摘要:
In this paper we present a grid of stellar evolution models, computed with an up-to-date physical description of the internal structure, using the Code d'Evolution Stellaire Adaptatif et Modulaire (CESAM). The evolutionary sequences span from the pre-main sequence to the beginning of the Red Giant Branch and cover an interval of mass typical for low and intermediate mass stars. The chemical composition (both helium and metal abundance) is the solar one. The frequencies of oscillation, computed for specific stellar models of the grid using the Porto Oscillations Code (POSC), are also provided. This work was accomplished in order to support the preparation of the CoRoT mission within the Evolution and Seismic Tools Activity (CoRoT/ESTA). On the other hand, the grid can also be used, more generally, to interpret the observational properties of either individual stars or stellar populations. The grids (data and documentation) can be found at http://www.astro.up.pt/corot/models/cesam
