Closed Form Solutions To Bosonic Perturbations In General Relativity
Arthur Suvorov, Anthony W. C. Lun
We present some results regarding metric perturbations in general relativity and other metric theories of gravity. In particular, using the Newman Penrose variables, we write down…
Electrostatic Potential of a Point Charge in a Brans-Dicke Reissner-Nordstrom Field
Maya Watanabe, A. W. C Lun
We consider the Brans-Dicke Reissner-Nordstrom spacetime in isotropic coordinates and the electrostatic field of an electric point charge placed outside its surface of inversion. W…
Gravitational collapse of plasmas in General Relativity
Paul Lasky, Anthony Lun
We provide a covariant derivation of plasma physics coupled to gravitation by utilizing the 3+1 formulation of general relativity, including a discussion of the Lorentz force law.…
1+1+2 Electromagnetic perturbations on general LRS space-times: Regge-Wheeler and Bardeen-Press equations
R. B. Burston, A. W. C. Lun
We use the, covariant and gauge-invariant, 1+1+2 formalism developed by Clarkson and Barrett, and develop new techniques, to decouple electromagnetic (EM) perturbations on arbitrar…
Gravitational collapse of spherically symmetric plasmas in Einstein-Maxwell spacetimes
Paul Lasky, Anthony Lun
We utilize a recent formulation of a spherically symmetric spacetime endowed with a general decomposition of the energy momentum tensor [Phys. Rev. D, 75, 024031 (2007)] to derive…
Spherically Symmetric Gravitational Collapse of General Fluids
Paul Lasky, Anthony Lun
We express Einstein's field equations for a spherically symmetric ball of general fluid such that they are conducive to an initial value problem. We show how the equations reduce t…
