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…

Evolution of self-gravitating fluid spheres involving ghost stars
L. Herrera, A. Di Prisco, J. Ospino
Exact solutions are presented which describe, either the evolution of fluid distributions corresponding to a ghost star (vanishing total mass), or describing the evolution of fluid…

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…
