| contents | A new formalism in general relativity with a linear response relation between perturbed Einstein tensor and the stress-energy tensor is presented. Basic concepts are borrowed from statistical physics and theory of stochastic processes by extending them for a spacetime structure. We show qualitatively new results of the first applications which lay foundations for a sub-hydro mesoscopic theory in dense matter relativistic stars. This will enable one to probe structure and phenomena at intermediate scales in relativistic stars and exotic fluids that they are made up of. The overall aim is to build foundations for studying dynamical equilibrium and non-equilibrium properties of astrophysical bodies based on stochastic correlations of perturbations of spacetime and matter fields. This will add to the present literature on asteroseismology a new insight in a significant way.It is also expected that this will lead to direct or indirect observational consequences of meso scale physics under extreme conditions present in the exotic objects. |
