论文摘要
根据奇怪的夸克（Quark Matter）假设，脉冲星实际上可能是由自我结合的奇怪夸克物质组成的奇怪星星。与普通中子恒星不同的奇怪恒星的正常物质外壳由强场上的电场支撑。然后在外壳和奇怪的夸克核之间呈现差距。因此，奇特的核心壳振荡可能发生在一个奇怪的恒星中，这可能会产生独特的引力波。在本文中，使用刚性模型得出了这种引力波的波形。我们发现，即使对于下一代探测器，重力波非常弱且无法检测。因此，奇怪的恒星的地震学不受核心壳振荡的影响。观察者将不得不搜索其他效果，以诊断地壳的存在。
According to the strange quark matter hypothesis, pulsars may actually be strange stars composed of self-bound strange quark matter. The normal matter crust of a strange star, unlike that of a normal neutron star, is supported by a strong electric field. A gap is then presented between the crust and the strange quark core. Therefore, peculiar core-crust oscillation may occur in a strange star, which can produce distinctive gravitational waves. In this paper, the waveforms of such gravitational waves are derived using a rigid model. We find that the gravitational waves are extremely weak and undetectable, even for the next-generation detectors. Therefore, the seismology of a strange star is not affected by the core-crust oscillation. Observers will have to search for other effects to diagnose the existence of the crust.
