摘要

本文对非线性重力核声波(激波)在由非惯性简并电子和惯性非简并重核组成的磁化简并量子等离子体中的传播进行了严密的理论研究。为了研究这些激波在等离子体系统中的非线性传播,采用了著名的约化微扰技术。推导了Burgers方程,得到了相应的激波结构解,并对激波剖面进行了数值分析。耗散力是重力核声波(GNAWs)形成的主要原因。我们还研究了这些GNAWs的基本性质(振幅、宽度、陡度等),这些性质受到等离子体种类的运动粘度、倾角和数量密度的显著改变。从我们目前的研究中获得的结果可以应用于天体物理致密物体,如白矮星和中子星。

Obliquely propagating gravito-nucleus acoustic waves in astrophysical degenerate quantum plasmas

A rigorous theoretical investigation has been made on the propagation of nonlinear gravito-nucleus acoustic waves (shock waves) in a magnetized degenerate quantum plasma, whose constituents are noninertial degenerate electrons and inertial nondegenerate heavy nuclei. To study the nonlinear propagation of these shock waves in the plasma system under consideration, the well-known reductive perturbation technique is used. The Burgers equation is derived and the associated shock structure solution is obtained to analyze the shock profile numerically. The dissipative force is responsible for the formation of the gravito-nucleus acoustic waves (GNAWs). The basic properties (amplitude, width, steepness, etc.) of these GNAWs have also been studied, which are significantly modified by the variation of kinematic viscosity, obliqueness, and number density of the plasma species. The results obtained from our present investigation can be applied to astrophysical compact objects like white dwarfs and neutron stars.
