Geometry of charged rotating discs of dust in Einstein-Maxwell theory
David Rumler, Andreas Kleinwächter, Reinhard Meinel
Within the framework of Einstein-Maxwell theory geometric properties of charged rotating discs of dust, using a post-Newtonian expansion up to tenth order, are discussed. Investiga…
On the black hole limit of rotating discs and rings
Andreas Kleinwächter, Hendrick Labranche, Reinhard Meinel
Solutions to Einstein's field equations describing rotating fluid bodies in equilibrium permit parametric (i.e. quasi-stationary) transitions to the extreme Kerr solution (outside…
Equilibrium Configurations of Homogeneous Fluids in General Relativity
M. Ansorg, T. Fischer, A. Kleinwächter +3
By means of a highly accurate, multi-domain, pseudo-spectral method, we investigate the solution space of uniformly rotating, homogeneous and axisymmetric relativistic fluid bodies…
Relativistically rotating dust
Gernot Neugebauer, Andreas Kleinwächter, Reinhard Meinel
Dust configurations play an important role in astrophysics and are the simplest models for rotating bodies. The physical properties of the general--relativistic global solution for…
Highly accurate calculation of rotating neutron stars: Detailed description of the numerical methods
M. Ansorg, A. Kleinwächter, R. Meinel
We give a detailed description of the recently developed multi-domain spectral method for constructing highly accurate general-relativistic models of rapidly rotating stars. For bo…
Uniformly rotating axisymmetric fluid configurations bifurcating from highly flattened Maclaurin spheroids
Marcus Ansorg, Andreas Kleinwächter, Reinhard Meinel
We give a thorough investigation of sequences of uniformly rotating, homogeneous axisymmetric Newtonian equilibrium configurations that bifurcate from highly flattened Maclaurin sp…
Dirichlet Boundary Value Problems of the Ernst Equation
Marcus Ansorg, Andreas Kleinwächter, Reinhard Meinel +1
We demonstrate how the solution to an exterior Dirichlet boundary value problem of the axisymmetric, stationary Einstein equations can be found in terms of generalized solutions of…
