Influence of electron inertia on gravitational instability of viscous partially ionized radiative quantum plasma

ABSTRACT

The effect of electron inertia on gravitational instability is studied of viscous partially ionized radiative quantum plasma. The quantum hydrodynamic model used various problems related to gravitational instability. The general dispersion relation is derived using normal mode analysis and discussed in the parallel and perpendicular propagation. The condition of instability and growth rate of the system is modified due to the presence of these parameters. We examined that from the curves all considered parameter has a stabilized or destabilized effect on the gravitational instability of the system.
