Non-spherical sources of Schwarzschild space-time
J. L. Hernández-Pastora, L. Herrera
While it is known that any spherical fluid distribution may only source the spherically symmetric Schwarzschild space-time, the inverse is not true. Thus, in this manuscript, we fi…
Complexity and simplicity of self-gravitating fluids
L. Herrera
We review a recently proposed definition of complexity of the structure of self--gravitating fluids \cite{ch1}, and the criterium to define the simplest mode of their evolution. We…
Expansion-free dissipative fluid spheres: Analytical models
L. Herrera, A. Di Prisco, J. Ospino
We search exact analytical solutions of spherically symmetric dissipative fluid distributions satisfying the vanishing expansion condition (vanishing expansion scalar ). To do s…
Non-static hyperbolicallly symmetric fluids
L. Herrera
We present the general properties of dynamic dissipative fluid distribution endowed with hyperbolical symmetry. All the equations required for its analysis are exhibited and used t…
Non-static fluid spheres admitting a conformal Killing vector: Exact solutions
L. Herrera, A. Di Prisco, J. Ospino
We carry on a general study on non--static spherically symmetric fluids admitting a conformal Killing vector (CKV). Several families of exact analytical solutions are found for dif…
Hyperbolically symmetric versions of Lemaitre-Tolman-Bondi spacetimes
L. Herrera, A. Di Prisco, J. Ospino
We study fluid distributions endowed with hyperbolical symmetry, which share many common features with Lemaitre-Tolman-Bondi (LTB) solutions (e.g. they are geodesic, shearing, non-…
