  A linear response relation between metric and fluid perturbations driven by a
background noise source is used as a framework for obtaining non-radial polar
perturbations in dense matter relativistic stars. The perturbations carry a
generalized stochastic nature as solutions to the classical Einstein-Langevin
equation which has been recently proposed. The significance of these stochastic
non-radial polar perturbations lies at probing the intermediate sub-hydro
scales inside the dense fluid. This study extends towards a
non-equilibrium/near-equilibrium statistical mechanics study for relativistic
star interiors. We address the non-radial polar perturbations in stars which
are important from the point of view of detection in future. A generalized
stochastic noise which originates as the remnant of collapse mechanism in
isolated star is expected to give rise to such stochastic polar perturbations
at intermediate sub-hydro scales. More specifically it is the interplay between
the degeneracy pressure of exotic matter and the gravitational pressure that
gives rise to the seeds of stochastic effects or noise in the background of the
gravitating body towards the near-equilibrium configuration.
