General relativistic neutrino transport using spectral methods
Bruno Peres, Andrew Jason Penner, Jerome Novak +1
We present a new code, Lorene's Ghost (for Lorene's gravitational handling of spectral transport) developed to treat the problem of neutrino transport in supernovae with the use of…
Ultrarelativistic Bondi--Hoyle Accretion I: Axisymmetry
Andrew J. Penner
An ultrarelativistic relativistic study of axisymmetric Bondi--Hoyle accretion onto a moving Kerr black hole is presented. The equations of general relativistic hydrodynamics are s…
Crustal failure during binary inspiral
A. J. Penner, N. Andersson, D. I. Jones +2
We present the first fully relativistic calculations of the crustal strain induced in a neutron star by a binary companion at the late stages of inspiral, employing realistic equat…
Tidal deformations of neutron stars: The role of stratification and elasticity
A. J. Penner, N. Andersson, L. Samuelsson +2
We discuss the response of neutron stars to the tidal interaction in a compact binary system, as encoded in the Love number associated with the induced deformation. This problem is…
General Relativistic Magnetohydrodynamic Bondi--Hoyle Accretion
Andrew J Penner
In this paper we present a fully relativistic study of axisymmetric magnetohydrodynamic Bondi--Hoyle accretion onto a moving Kerr black hole. The equations of general relativistic…
Generalised superradiant scattering
Mauricio Richartz, Silke Weinfurtner, A. J. Penner +1
We analyse the necessary and sufficient conditions for the occurrence of superradiance. Starting with a wave equation we examine the possibility of superradiance in terms of an eff…
