A thermodynamic approach to the T-models
arXiv:2106.01015 · doi:10.1103/PhysRevD.104.024038
Abstract
The perfect fluid solutions admitting a group G of isometries acting on orbits S whose curvature has a gradient which is tangent to the fluid flow (T-models) are studied from a thermodynamic approach. All the admissible thermodynamic schemes are obtained, and the solutions compatible with the generic ideal gas equation of state are studied in detail. The possible physical interpretation of some previously known T-models is also analyzed.
