造父变星。我们如何以及如何了解他们

Cepheids in Eclipsing Binaries. What and How We Can Learn About Them

Bogumił Pilecki

摘要:

具有脉动成分的双星系统为精确测量脉动恒星的最重要参数、研究它们的演化和检验脉动理论提供了独特的可能性。我将展示我们可以从分析这类系统中了解到什么,以及我们如何去做,并将特别注意质量、半径、p因子和距离的确定。虽然该方法的核心是基于双线食分光双星的观测,但借助于脉动理论,也可以测量单线食分光双星的绝对参数。

英文摘要:

Eclipsing binary systems with pulsating components offer a unique possibility to accurately measure the most important parameters of pulsating stars, to study their evolution, and to test the pulsation theory. I will show what we can learn about the pulsating stars from the analysis of such systems and how we can do it. Special attention will be paid to the mass, radius, p-factor, and distance determination. Although the core of the method is based on the observations of double-lined eclipsing spectroscopic binaries, with the help of the pulsation theory, it is possible to measure absolute parameters for single-lined binaries also.
