Classical dynamics and stability of collapsing thick shells of matter
G. L. Alberghi, R. Casadio, D. Fazi
We study the collapse towards the gravitational radius of a macroscopic spherical thick shell surrounding an inner massive core. This overall electrically neutral macroshell is com…
Thermodynamics of a collapsing shell in an expanding Universe
G. L. Alberghi, R. Casadio, G. Venturi
We describe the quasi-static collapse of a radiating, spherical shell of matter in de Sitter space-time using a thermodynamical formalism. It is found that the specific heat at con…
On the gravitational collapse in anti-de Sitter space-time
G. L. Alberghi, R. Casadio
We study the semiclassical evolution of a self-gravitating thick shell in Anti-de Sitter space-time. We treat the matter on the shell as made of quantized bosons and evaluate the b…
Thermodynamics for radiating shells in anti-de Sitter space-time
G. L. Alberghi, R. Casadio, G. Venturi
A thermodynamical description for the quasi-static collapse of radiating, self-gravitating spherical shells of matter in anti-de Sitter space-time is obtained. It is shown that the…
