一些CoRoT亮点-掌握恒星物理学及其他

Some CoRoT highlights - A grip on stellar physics and beyond

E. Michel, A. Baglin

摘要:

大约两年前,也就是2009年,第一届CoRoT研讨会是展示和讨论前所未有的数据的机会,这些数据揭示了恒星在微星等水平上的行为。从那时起,观察一直在进行,目标样本不断丰富,对这些数据的分析工作不断产生一流的结果。这些分析为解决恒星结构和演化的公开问题提供了材料,并测试了恒星中如此多的物理过程。基于这些材料,越来越多的解释研究正在出版,解决各种关键问题:混合核的延伸,近地表对流区的结构,磁活动,质量损失,......结论将需要在更大的基础上(仍在建设中)对结果进行交叉比较,但在第二届CoRoT研讨会上,已经有可能展示各种现有结果如何在一个通用框架中发生,并有助于完成我们最初的科学目标。一些结果已经揭示了在全球范围内考虑恒星和行星的潜在兴趣,正如本次研讨会上的几次演讲所强调的那样。考虑红巨星领域的快速进展,并看看它们如何说明空间测光在恒星物理学领域之外,在银河系动力学和演化等连接领域的巨大潜力,也是很有吸引力的。

英文摘要:

About 2 years ago, back in 2009, the first CoRoT Symposium was the occasion to present and discuss unprecedented data revealing the behaviour of stars at the micromagnitude level. Since then, the observations have been going on, the target sample has enriched and the work of analysis of these data keeps producing first rank results. These analyses are providing the material to address open questions of stellar structure and evolution and to test the so many physical processes at work in stars. Based on this material, an increasing number of interpretation studies is being published, addressing various key aspects: the extension of mixed cores, the structure of near surface convective zones, magnetic activity, mass loss, ... Definitive conclusions will require cross-comparison of results on a larger ground (still being built), but it is already possible at the time of this Second CoRoT Symposium, to show how the various existing results take place in a general framework and contribute to complete our initial scientific objectives. A few results already reveal the potential interest in considering stars and planets globally, as it is stressed in several talks at this symposium. It is also appealing to consider the fast progress in the domain of Red Giants and see how they illustrate the promising potential of space photometry beyond the field of stellar physics, in connex fields like Galactic dynamics and evolution.
