Elastic stars in general relativity: IV. Axial perturbations
Max Karlovini, Lars Samuelsson
This is the fourth paper in a series that attempt to put forward a consistent framework for modelling solid regions in neutron stars. Here we turn our attention to axial perturbati…
Charged black holes in compactified spacetimes
Max Karlovini, Rikard von Unge
We construct and investigate a compactified version of the four-dimensional Reissner-Nordstrom-NUT solution, generalizing the compactified Schwarzschild black hole that has been pr…
Elastic Stars in General Relativity: III. Stiff ultrarigid exact solutions
Max Karlovini, Lars Samuelsson
We present an equation of state for elastic matter which allows for purely longitudinal elastic waves in all propagation directions, not just principal directions. The speed of the…
Elastic Stars in General Relativity: II. Radial perturbations
Max Karlovini, Lars Samuelsson, Moundheur Zarroug
We study radial perturbations of general relativistic stars with elastic matter sources. We find that these perturbations are governed by a second order differential equation which…
Elastic Stars in General Relativity: I. Foundations and Equilibrium Models
Max Karlovini, Lars Samuelsson
The aim of this paper is twofold. First, we set up the theory of elastic matter sources within the framework of general relativity in a self-contained manner. The discussion is pri…
A unified treatment of quartic invariants at fixed and arbitrary energy
Max Karlovini, Giuseppe Pucacco, Kjell Rosquist +1
Two-dimensional Hamiltonian systems admitting second invariants which are quartic in the momenta are investigated using the Jacobi geometrization of the dynamics. This approach all…
