用于星震学和银河系研究的光度恒星参数

Photometric stellar parameters for asteroseismology and Galactic studies

Luca Casagrande

摘要:

天文地震学有能力提供恒星的性质,否则将无法获得,如半径,质量和恒星的年龄。当耦合这些信息与经典的恒星参数,如金属丰度,有效温度和角直径的测定,强大的新的诊断恒星和银河系的研究可以获得。我回顾了不同的光度系统和过滤器进行重要的信息,经典的恒星参数,这些参数的准确性可以推导出来,并总结了一些校准文献中的晚型恒星。最近的努力,结合经典和asterosephic参数进行了讨论,并强调其独特性的interactions。

英文摘要:

Asteroseismology has the capability of delivering stellar properties which would otherwise be inaccessible, such as radii, masses and thus ages of stars. When coupling this information with classical determinations of stellar parameters, such as metallicities, effective temperatures and angular diameters, powerful new diagnostics for both stellar and Galactic studies can be obtained. I review how different photometric systems and filters carry important information on classical stellar parameters, the accuracy at which those parameters can be derived, and summarize some of the calibrations available in the literature for late-type stars. Recent efforts in combining classical and asteroseismic parameters are discussed, and the unique- ness of their intertwine is highlighted.
