Thermodynamics of a collapsing shell in an expanding Universe
arXiv:gr-qc/0409118 · doi:10.1016/j.physletb.2004.09.063
Abstract
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 constant area and other thermodynamical quantities exhibit singularities related to phase transitions during the collapse.
