极低质量恒星:结构和演化特性

Very Low-Mass Stars: structural and evolutionary properties

Santi Cassisi

摘要:

我们简要回顾了极低质量恒星的主要物理和结构特性。最重要的改进所需的恒星模型计算的物理输入进行了讨论。我们展示了一些与观测测量的比较,包括色-星等图,质量-光度关系和质量-半径关系,以揭示目前的理论框架和观测之间的一致性。

英文摘要:

We briefly review the main physical and structural properties of Very Low-Mass stars. The most important improvements in the physical inputs required for the stellar models computations are also discussed. We show some comparisons with observational measurements concerning both the Color-Magnitude diagrams, mass-luminosity relations and mass-radius one, in order to disclose the level of agreement between the present theoretical framework and observations.
