真实结构旋转恒星动力潮汐的广义简正模方法及其应用

A new general normal mode approach to dynamic tides in rotating stars with realistic structure and its applications

P. B. Ivanov, J. C. B. Papaloizou, S. V. Chernov

摘要:

我们回顾了Ivanov,Papaloizou $\&$ Ivanov(2013)和Pakov,Papaloizou $\&$ Ivanov(2013)提出的动力潮汐统一简正模方法的最新结果。我们的形式主义,可以使用的潮汐相互作用,主要是由正常模式的一颗星与可识别的规则频谱的低频模式。我们在文本中提供了对周期轨道和抛物轨道都有效的潮汐能和角动量转移的基本表达式,以及由于粘性和/或非线性效应而对正模阻尼效率的不同假设,并讨论了对联星和近轨太阳系外行星的应用。

英文摘要:

We review our recent results on a unified normal mode approach to dynamic tides proposed in Ivanov, Papaloizou $\&$ Chernov (2013) and Chernov, Papaloizou $\&$ Ivanov (2013). Our formalism can be used whenever the tidal interactions are mainly determined by normal modes of a star with identifiable regular spectrum of low frequency modes. We provide in the text basic expressions for tidal energy and angular momentum transfer valid both for periodic and parabolic orbits, and different assumptions about efficiency of normal mode damping due to viscosity and/or non-linear effects and discuss applications to binary stars and close orbiting extrasolar planets.
