Non-singular G2 stiff fluid cosmologies
L. Fernandez-Jambrina, L. M. Gonzalez-Romero
In this paper we analyse Abelian diagonal orthogonally transitive spacetimes with spacelike orbits for which the matter content is a stiff perfect fluid. The Einstein equations are…
High Order Relativistic Corrections To Keplerian Motion
L. Fernandez-Jambrina, C. A. Hoenselaers
The first terms of the general solution for an asymptotically flat stationary axisymmetric vacuum spacetime endowed with an equatorial symmetry plane are calculated from the corres…
Singularity-Free Cylindrical Cosmological Model
L. Fernandez-Jambrina
A cylindrically symmetric perfect fluid spacetime with no curvature singularity is shown. The equation of state for the perfect fluid is that of a stiff fluid. The metric is diagon…
Differential Form Approach for Stationary Axisymmetric Maxwell Fields in General Relativity
L. Fernandez-Jambrina, F. J. Chinea
A formulation for stationary axisymmetric electromagnetic fields in general relativity is derived by casting them into the form of an anisotropic fluid. Several simplifications of…
Moment Density of Zipoy's Dipole Solution
L. Fernandez-Jambrina
Zipoy used spheroidal coordinates to construct a family of static axisymmetric gravitational fields included in Weyl's class. We calculate the mass moment source for the dipole sol…
Non-singular radiation cosmological models
L. Fernandez-Jambrina, L. M. Gonzalez-Romero
In this paper we analyse the possibility of constructing singularity-free inhomogeneous cosmological models with a pure radiation field as matter content. It is shown that the cond…
