Ghost stars in general relativity
L. Herrera, A. Di Prisco, J. Ospino
We explore an idea put forward many years ago by Zeldovich and Novikov concerning the existence of compact objects endowed with arbitrarily small mass. The energy-density of such o…
Cracking and complexity of self-gravitating dissipative compact objects
L. Herrera, A. Di Prisco
The concept of cracking refers to the tendency of a fluid distribution to "split'', once it abandons the equilibrium. In this manuscript we develop a general formalism to describe…
The post--quasi-static approximation: An analytical approach to gravitational collapse
L. Herrera, A. Di prisco, J. Ospino
A semi--numerical approach proposed many years ago for describing gravitational collapse in the post--quasi--static approximation, is modified in order to avoid the numerical integ…
Irreversibility and gravitational radiation: A proof of Bondi's conjecture
L. Herrera, A. Di Prisco, J. Ospino
It is shown that the evolution of an axially and reflection symmetric fluid distribution, satisfying the Tolman condition for thermal equilibrium, is not accompanied by the emissio…
