The impact of electron plasma frequency on Jeans instability of radiative quantum plasma

EasyChair Preprint 2059

Abstract

In this paper, we have studied the impact of electron plasma frequency on Jeans instability of radiative magnetized quantum plasma. The analysis is carried out within the framework of normal mode analysis technique which is modified due to the contribution of electron plasma frequency. The dispersion relation is reduced for both longitudinal and transverse mode of propagation. The condition of Jeans instability is modified due to the presence of magnetic field and electron plasma frequency in the transverse mode of propagation. From the curve, it is clear that electron plasma frequency has destabilizing influence in the system but the presence of a quantum parameter is reduced the destabilizing effect of electron plasma frequency and stabilized the system. The research will help to understand stellar evolution in astronomical plasma.

Keyphrases: Electron plasma frequency, Quantum correction, Radiative heat-loss function, electrical resistivity, magnetic field.
