Temperature Evolution Law of Imperfect Relativistic Fluids
Abstract
The firstorder general relativistic theory of a generic dissipative (heatconducting, viscous, particlecreating) fluid is rediscussed from a unified covariant frameindependent point of view. By generalizing some previous works in the literature, we derive a formula for the temperature variation rate, which is valid both in Eckart's (particle) and in the LandauLifshitz (energy) frames. Particular attention is paid to the case of gravitational particle creation and its possible crosseffect with the bulk viscosity mechanism.
