旋转恒星中的正则模
Regular modes in rotating stars
摘要：
尽管有越来越多的观测数据，恒星声振荡模式没有得到很好的理解，一旦旋转不能处理微扰。以类似于量子物理学中的半经典理论的方式，我们使用声射线动力学来建立最容易观察和识别的规则模式子集的渐近理论。与2D数值模拟的振荡在多变的恒星的比较表明，这些模式的频率和振幅分布可以准确地描述了几乎所有的旋转速率的渐近理论。光谱主要由两个量子数表征，从观测到的光谱中提取它们可以获得恒星内部的信息。
英文摘要：
Despite more and more observational data, stellar acoustic oscillation modes are not well understood as soon as rotation cannot be treated perturbatively. In a way similar to semiclassical theory in quantum physics, we use acoustic ray dynamics to build an asymptotic theory for the subset of regular modes which are the easiest to observe and identify. Comparisons with 2D numerical simulations of oscillations in polytropic stars show that both the frequency and amplitude distributions of these modes can accurately be described by an asymptotic theory for almost all rotation rates. The spectra are mainly characterized by two quantum numbers; their extraction from observed spectra should enable one to obtain information about stellar interiors.
