摘要

The problem of thermal instability is investigated for partially ionized thermal plasma, which has a connection in astrophysical condensations and is responsible for formation of objects in an astrophysical plasma environment. Using relevant linearized perturbation equations, a general dispersion relation has been derived with the help of the normal mode analysis technique. To argue the consequences of different physical parameters on the thermal instability criterion, the general dispersion relation is reduced in longitudinal and transverse modes of propagation. Effects of radiative heat-loss function, finite ion Larmor radius (FLR) corrections, and collisions with neutrals on the thermal instability criterion of the system are discussed. The conditions of thermal instability are derived for a heat-loss function with thermal conductivity and FLR corrections for some particular cases. The Routh-Hurwitz criterion has been used to discuss the stability of the system. Numerical calculations have been performed to discuss the dependence of the growth rate of the thermal instability on the various physical parameters. The viscosity, FLR corrections, magnetic field, and neutral collision have a stabilizing influence; whereas, permeability has a destabilizing influence on the thermal instability of the system. Our results are helpful for understanding the process of MHD flow of fluid through a porous medium and structure formation in an astrophysical plasma environment.
