Dynamical instability and the expansion-free condition
L. Herrera, G. Le Denmat, N. O. Santos
We study the dynamical instability of a spherically symmetric anisotropic fluid which collapses adiabatically under the condition of vanishing expansion scalar. The Newtonian and p…
Cavity evolution in relativistic self-gravitating fluids
L. Herrera, G. Le Denmat, N. O. Santos
We consider the evolution of cavities within spherically symmetric relativistic fluids, under the assumption that proper radial distance between neighboring fluid elements remains…
Expansion-Free Evolving Spheres Must Have Inhomogeneous Energy Density Distributions
L. Herrera, G. Le Denmat, N. O. Santos
In a recent paper a systematic study on shearing expansion-free spherically symmetric distributions was presented. As a particular case of such systems, the Skripkin model was ment…
Nonadiabatic charged spherical gravitational collapse
A. Di Prisco, L. Herrera, G. Le Denmat +2
We present a complete set of the equations and matching conditions required for the description of physically meaningful charged, dissipative, spherically symmetric gravitational c…
