Geodesics in the Gamma spacetime
L. Herrera, Filipe M. Paiva, N. O. Santos
Circular and radial geodesics are studied in the spacetime described by the metric. Their behaviour is compared with the spherically symmetric situation, bringing out the sensi…
The Levi-Civita spacetime as a limiting case of the Gamma spacetime
L. Herrera, Filipe M. Paiva, N. O. Santos
It is shown that the Levi-Civita metric can be obtained from a family of the Weyl metric, the Gamma metric, by taking the limit when the length of its Newtonian image source tends…
The Active Gravitational Mass of a Heat Conducting Sphere Out of Hydrostatic Equilibrium
L. Herrera, A. Di Prisco
We obtain an expression for the active gravitational mass of a relativistic heat conducting fluid, just after its departure from hydrostatic equilibrium, on a time scale of the ord…
Thermal conduction before relaxation in slowly rotating fluids
L. Herrera, A. Di Prisco, J. Martinez
For slowly rotating fluids, we establish the existence of a critical point similar to the one found for non-rotating systems. As the fluid approaches the critical point, the effect…
