Gravitational Waves from the Pulsar Magnetosphere
Ioannis Contopoulos, Demosthenes Kazanas, Demetrios B. Papadopoulos
We investigate the generation of gravitational waves from the rotation of an orthogonal pulsar magnetosphere in flat space time. We calculate the first order metric perturbation du…
The magnetic Rayleigh-Taylor instability around astrophysical black holes
Demetrios Papadopoulos, Ioannis Contopoulos
We investigate the development of the magnetic Rayleigh-Taylor instability at the inner edge of an astrophysical disk around a spinning central black hole. We solve the equations o…
Generating Solutions to the Einstein - Maxwell Equations
I. G. Contopoulos, F. P. Esposito, K. Kleidis +2
The Einstein-Maxwell (E-M) equations in a curved spacetime that admits at least one Killing vector are derived, from a Lagrangian density adapted to symmetries. In this context, an…
Radiation from charged particles on eccentric orbits in a dipolar magnetic field around a Schwarzschild black hole
Demetrios B. Papadopoulos, Ioannis Contopoulos, Kostas D. Kokkotas +1
We obtain an approximate solution for the motion of a charged particle around a Schwarzschild black hole immersed in a weak dipolar magnetic field. We focus on eccentric bound orbi…
Generating Solutions to the Einstein Field Equations
I. G. Contopoulos, F. P. Esposito, K. Kleidis +2
Exact solutions to the Einstein field equations may be generated from already existing ones (seed solutions), that admit at least one Killing vector. In this framework, a space of…
