本文对中子星的径向振荡模式作了新的研究。这项研究补充和纠正了早期的径向振荡研究。我们提出了一个广泛的列表的频率最常见的状态方程和一些最近的。为了检查的准确性,我们使用两种不同的数值方案,产生相同的结果。这项工作的刺激来自于发展完全非线性爱因斯坦方程的团体的需要,以便从微扰理论中获得可靠的结果进行比较。
We present a new survey of the radial oscillation modes of neutron stars. This study complements and corrects earlier studies of radial oscillations. We present an extensive list of frequencies for the most common equations of state and some more recent ones. In order to check the accuracy, we use two different numerical schemes which yield the same results. The stimulation for this work comes from the need of the groups that evolve the full nonlinear Einstein equation to have reliable results from perturbation theory for comparison.
