Impacts of Rotation Radiative Heat-loss Functions Porosity with FLR Corrections on Transverse Thermal Instability of Finitely Conducting Plasma in Interstellar Medium (ISM)

Abstract

Abstract The impact of rotation, finite ion Larmor radius (FLR) corrections and porosity on the thermal criterion of instability of infinite uniform plasma has been carried out by including the effects of radiative heat-loss function and thermal conductivity. The universal dispersion relation is obtained by resources of the normal mode analysis technique by the use of suitable linearized perturbation equations of the problem. This dispersion relation is additionally condenses for rotation axis parallel and perpendicular to the magnetic field for transverse wave propagation. Thermal instability criterion set up the stability of the medium. Numerical computations have been carried out to show the impacts of different parameters on the growth rate of the thermal instability. We conclude that rotation, FLR corrections and medium porosity stabilize the growth rate of the system in the transverse mode of propagation. Our result reveals that the rotation, porosity and FLR corrections affect the dens molecular clouds arrangement and star development in interstellar medium.
