相对论轨道和引力波的重磁修正

Relativistic orbits and Gravitational Waves from gravitomagnetic corrections

Salvatore Capozziello, Mariafelicia De Laurentis, Luca Forte, Fabio Garufi, Leopoldo Milano

摘要:

考虑到高阶近似引起的重磁效应的轨道相对论理论的修正进行了讨论。除了广义相对论的标准近星点效应外,还发现了一种新的章动效应,这种章动效应是由于${\displaystyle c^{-3}}$轨道修正引起的。根据这种新章动效应的存在,我们在四极近似下研究了致密天体(中子星(NS或BH))在大质量黑洞(MBH)的引力场中被俘获时所发射的引力波形。我们用数值方法研究了发射的引力波的振幅。我们的结论是,我们研究的影响可能是未来的空间激光干涉GW天线LISA的兴趣。

英文摘要:

Corrections to the relativistic theory of orbits are discussed considering higher order approximations induced by gravitomagnetic effects. Beside the standard periastron effect of General Relativity (GR), a new nutation effect was found due to the ${\displaystyle c^{-3}}$ orbital correction. According to the presence of that new nutation effect we studied the gravitational waveforms emitted through the capture in a gravitational field of a massive black hole (MBH) of a compact object (neutron star (NS) or BH) via the quadrupole approximation. We made a numerical study to obtain the emitted gravitational wave (GW) amplitudes. We conclude that the effects we studied could be of interest for the future space laser interferometric GW antenna LISA.
