Abstract: |
Gravity is known to have important effects on electromagnetic fields in the environs of compact objects. After a brief introduction to electromagnetism in general relativity, we focus on the interaction between gravitational waves (GWs) and magnetohydrodynamic (MHD) waves. We use the ideal MHD approximation, and the familiar 1+3 split of the reference frame, which allows a direct interpretation of the results by the physical observer. We show how fast magneto-sonic waves and Alfvén waves can grow in a magneto-plasma by action of gravitational waves on the ambient magnetic field in the far-field approximation for various configurations of ambient field and wave directions. |
