Query: Matter sources of gauge thermodynamics   A unified gauge approach to both, dynamics and thermodynamics involving
gravity, is developed from the local realization of the Poincar\'e group as a
particular instance of a spacetime group including translations. The formalism
is applied to study the physical features of the spherical non-rotating matter
source of an inner Schwarzschild metric.
