Gravitationally Driven Electromagnetic Perturbations of Neutron Stars and Black Holes

Understand

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.
