On the Role of Electric Charge and Cosmological Constant in Structure Scalars
L. Herrera, A. Di Prisco, J. Ibañez
The physical meaning of structure scalars is analyzed for charged dissipative spherical fluids and for neutral dust in the presence of cosmological constant. The role played by suc…

Tilted Lemaitre-Tolman-Bondi Spacetimes: Hydrodynamic and Thermodynamic Properties
L. Herrera, A. Di Prisco, J. Ibañez
We consider Lemaitre-Tolman-Bondi spacetimes from the point of view of a tilted observer, i.e. one with respect to which the fluid is radially moving. The imperfect fluid and the c…

Expansion-Free Cavity Evolution: Some exact Analytical Models
A. Di Prisco, L. Herrera, J. Ospino +2
We consider spherically symmetric distributions of anisotropic fluids with a central vacuum cavity, evolving under the condition of vanishing expansion scalar. Some analytical solu…
