本文研究近距奇异行星与宿主奇异星的并合引力波,推导含磁场和倾角效应的波形模板,指出磁相互作用可显著加速并合并有望被现有及未来实验探测。

摘要:

根据奇异夸克物质假说,奇异行星可能存在,它们是由数量几乎相等的上夸克、下夸克和奇异夸克组成的行星质量天体。一颗奇异行星可以在非常近的轨道上绕其宿主奇异星运行。当它最终与宿主并合时,将产生强烈的引力波辐射。本文推导了并合过程的引力波形,并考虑了奇异星磁场对动力学的影响,同时也考虑了倾角的影响,进而推导了引力波形模板。研究发现,磁相互作用显著加快了并合过程。发生在银河系以及近邻星系中的此类奇异行星系统的并合事件,可被当前及未来的引力实验有效探测,这有望为检验奇异夸克物质假说和探测致密星磁场提供一种新方法。

英文摘要:

According to the strange quark matter hypothesis, strange planets may exist, which are planetary mass objects composed of almost equal numbers of up, down and strange quarks. A strange planet can revolve around its host strange star in a very close-in orbit. When it finally merges with the host, strong gravitational wave emissions will be generated. Here the gravitational waveforms are derived for the merging process, taking into account the effects of the strange star's magnetic field on the dynamics. Effects of the inclination angle are also considered. Templates of the gravitational waveforms are derived. It is found that the magnetic interactions significantly speed up the merging process. Coalescence events of such strange planetary systems occurring in our Galaxy as well as in local galaxies can be effectively detected by current and future gravitational experiments, which may hopefully provide a new method to test the strange quark matter hypothesis and probe the magnetic field of compact stars.
