Complexity hierarchies in Euclidean stars
L. Herrera, A. Di Prisco, J. Ospino
We establish a hierarchy of Euclidean stars according to their degree of complexity, as measured by the complexity factor and the complexity of the pattern of evolution. We conside…
The birth of a ghost star
L. Herrera, A. Di Prisco, J. Ospino
We present a model of an evolving spherically symmetric dissipative self-gravitating fluid distribution which tends asymptotically to a ghost star, meaning that the end state of su…
Dynamics of hyperbolically symmetric fluids
L. Herrera, A. Di Prisco, J. Ospino
We study the general properties of dissipative fluid distributions endowed with hyperbolical symmetry. Their physical properties are analyzed in detail. It is shown that the energy…
Complexity of the Bondi metric
L. Herrera, A. Di Prisco, J. Carot
A recently introduced concept of complexity for relativistic fluids is extended to the vacuum solutions represented by the Bondi metric. A complexity hierarchy is established, rang…
Tilted shear-free axially symmetric fluids
L. Herrera, A. Di Prisco, J. Carot
We carry on a systematic study of the physical properties of axially symmetric fluid distributions, which appear to be geodesic, shear--free, irrotational, non--dissipative and pur…
Physical infeasibility of geodesic dissipative dust as a source of gravitational radiation
L. Herrera, A. Di Prisco, J. Ospino
Using a framework based on the 1+3 formalism, we show that a source represented by a geodesic, dissipative, rotational dust, endowed with axial and reflection symmetry, violates re…
