An approximate global stationary axisymmetric solution of the Einstein equations
J. Martin-Martin, A. Molina, E. Ruiz
In this work we present an approximate solution of the Einstein equations describing a global model for the gravitational field generated by a bounded, self-gravitating stationary…
On the discrepancy between two approaches to the equilibrium problem for spinning particles
V. S. Manko, E. Ruiz
We show that the absence of equilibrium states of two uncharged spinning particles located on the symmetry axis, revealed in an approximate approach recently employed by Bonnor, ca…
Admissible Lichnerowicz coordinates for the Schwarzschild metric
Jose Luis Hernandez-Pastora, Jesus Martin, Eduardo Ruiz
Global harmonic coordinates for the complete Schwarzschild metric are found for a more general case than that addressed in a previous work by Quan-Hui Liu. The supplementary consta…
On gyroscopic precession
José Luis Hernández-Pastora, Jesús Martín, Eduardo Ruiz
The vorticity of a congruence is often considered to be the rate of rotation for the precession of a gyroscope moving along a world-line belonging to that congruence. Our aim here…
