From geodesics of the multipole solutions to the perturbed Kepler problem
J. L. Hernandez-Pastora, J. Ospino
A static and axisymmetric solution of the Einstein vacuum equations with a finite number of Relativistic Multipole Moments (RMM) is written in MSA coordinates up to certain order o…
New Representation of some Static and Axisymmetric Vacuum Solutions
J. L. Hernandez-Pastora, J. Ospino
We solve the Einstein vacuum-equations for the case of static and axisymmetric solutions in a system of coordinates different from the Weyl standard one. We prove that there exists…
Lemaitre-Tolman-Bondi dust spacetimes: Symmetry properties and some extensions to the dissipative case
L. Herrera, A. Di Prisco, J. Ospino +1
We consider extensions of Lemaitre-Tolman-Bondi (LTB) spacetimes to the dissipative case. For doing that we previously carry out a systematic study on LTB. This study is based on t…
On the stability of the shear-free condition
L. Herrera, A. Di Prisco, J. Ospino
The evolution equation for the shear is reobtained for a spherically symmetric anisotropic, viscous dissipative fluid distribution, which allows us to investigate conditions for th…
