引力驱动的中子星和黑洞的电磁微扰

Gravitationally Driven Electromagnetic Perturbations of Neutron Stars and Black Holes

Hajime Sotani, Kostas D. Kokkotas, Pablo Laguna, Carlos F. Sopuerta

摘要:

中子星和黑洞的引力扰动是众所周知的引力辐射源。如果紧凑物体浸没在磁场中或被赋予磁场,则重力扰动将耦合到电磁扰动,并可能触发协同电磁特征。本文对中子星和黑洞的引力和电磁耦合扰动动力学进行了详细的解析计算。我们讨论了在这些情况下探测电磁波的前景,以及这些波提供有关其来源的信息的潜力。

英文摘要:

Gravitational perturbations of neutron stars and black holes are well known sources of gravitational radiation. If the compact object is immersed in or endowed with a magnetic field, the gravitational perturbations would couple to electromagnetic perturbations and potentially trigger synergistic electromagnetic signatures. We present a detailed analytic calculation of the dynamics of coupled gravitational and electromagnetic perturbations for both neutron stars and black holes. We discuss the prospects for detecting the electromagnetic waves in these scenarios and the potential that these waves have for providing information about their source.
