Axially symmetric static sources of gravitational field
J. L. Hernandez-Pastora, L. Herrera, J. Martin
A general procedure to find static and axially symmetric, interior solutions to the Einstein equations is presented. All the so obtained solutions, verify the energy conditions for…
Can rigidly rotating polytropes be sources of the Kerr metric?
J. Martin, A. Molina, E. Ruiz
We use a recent result by Cabezas et al. to build up an approximate solution to the gravitational field created by a rigidly rotating polytrope. We solve the linearized Einstein eq…
An approximate global solution of Einstein's equations for a finite body
J. A. Cabezas, J. Martin-Martin, A. Molina +1
We obtain an approximate global stationary and axisymmetric solution of Einstein's equations which can be considered as a simple star model: a self-gravitating perfect fluid ball w…
Singular sources in the Demianski-Newman spacetimes
V. S. Manko, J. Martin, E. Ruiz
The analysis of singular regions in the NUT solutions carried out in the recent paper (Manko and Ruiz, 2005 Class. Quantum Grav. 22, p.3555) is now extended to the Demianski-Newman…
Comparing metrics at large: harmonic vs quo-harmonic coordinates
J. M. Aguirregabiria, Ll. Bel, J. Martin +2
To compare two space-times on large domains, and in particular the global structure of their manifolds, requires using identical frames of reference and associated coordinate condi…
Approaches to the Monopole-Dynamic Dipole Vacuum Solution Concerning the Structure of its Ernst's Potential on the Symmetry Axis
J. L. Hernandez-Pastora, J. Martin, E. Ruiz
The FHP algorithm allows to obtain the relativistic multipole moments of a vacuum stationary axisymmetric solution in terms of coefficients which appear in the expansion of its Ern…
