论文摘要
新型的热退化等离子体模型（基于包含相对和热归化的无惯性电子物种，非相关和热退化的惯性光核物种以及固定的重核物种的系统，以及固定的重核物种）。已经研究了与热变性驱动的核 - 声波在这种热退化等离子体系统中传播的平面和非平面孤立结构的基本特征。使用的还原性扰动方法对小幅度孤立波有效。发现非平面圆柱形和球形几何形状，非和超偏见的电子物种，电子和光核物种的热和变性压力，光和重核的数量密度与基本特征相关的光和重核物种的数量密度相关（Viz spep，速度，稳定性）。波浪。所考虑的退化血浆模型是如此笼统和现实，以至于它不仅适用于天体物理紧凑型物体（如热白矮人），还适用于除电子和离子等离子体物种外，还适用于含有带正电荷的重物颗粒的空间等离子体系统。
The novel thermally degenerate plasma model (based on a system containing relativistically and thermally degenerate inertial-less electron species, non-relativistically and thermally degenerate inertial light nucleus species, and stationary heavy nucleus species) is considered. The basic features of planar and nonplanar solitary structures associated with the thermally degenerate pressure driven nucleus-acoustic waves propagating in such a thermally degenerate plasma system has been investigated. The reductive perturbation method, which is valid for small amplitude solitary waves, is used. It is found that the effects of nonplanar cylindrical and spherical geometries, non and ultra-relativistically degenerate electron species, thermal and degenerate pressures of electron and light nucleus species, and number densities of light and heavy nucleus species significantly modify the basic features (viz. speed, amplitude, and width) of the solitary potential structures associated with thermally degenerate pressure driven nucleus-acoustic waves. The degenerate plasma model under consideration is so general and realistic that it is applicable not only in astrophysical compact objects like hot white dwarfs, but also in space plasma systems like mesospheres containing positively charged heavy particles in addition to electron and ion plasma species.
