辐射热量损失函数和热导率的影响被考虑在分析旋转的影响,有限的离子半径拉莫尔(FLR)修正和孔隙度在无限均匀等离子体的热不稳定的标准。通过使用适当的线性化摄动方程的问题,正常模式分析方法可用于获得普遍的色散关系。横波传播的色散方程进一步凝聚为旋转坐标轴平行和垂直于磁场。建立了稳定的介质通过热不稳定性标准。不同的影响因素对热不稳定性的增长速度已经证明了数值计算。我们推断系统的增长速度在横向的传播模式是由旋转稳定,FLR调整,中等孔隙度。我们的发现证明旋转、孔隙度和FLR修正影响密集分子云和恒星形成的组织在星际介质中。

介绍

今天的等离子体物理科学研究的一个主要新兴主题在许多科学探索的领域。类似,天文学和空间科学一直在考虑等离子体不稳定几年了解小和大配置出现在星际介质。作为重要的循环控制外部变暖,辐射冷却在天体物理等离子体和星际介质,热不稳定性的研究正成为知名(ISM)。热不稳定性的存在可以解释大量的天体,包括星际云,太阳日珥,限制结构在行星状星云,等等。一个系统,可以成为冷由于辐射和流体减少热不稳定性的经历。此外,降低冷凝温度使得系统不平衡,使得密度,导致创建新的安排。一个系统可以变得热不稳定,即使它是稳定的除了引力不稳定,因为这种不稳定性的重要长度尺度小于其它动力不稳定,包括牛仔裤引力不稳定性。因此,可以断言,热不稳定性,而不是动力不稳定,负责小规模的物理基础结构。部分电离的粘性等离子体的热不稳定性与霍尔效应FLR修正通过多孔材料已经被一些研究人员研究了超过7年在天体物理对象和等离子体物理应用。结果,我们发现大量的学习完成magneto-thermal等离子体具有不同特征在不同假设。 In addition, the study of big and tiny astronomical objects, such as comets, meteorites, and interplanetary dust, is greatly impacted by the problem of thermal instability of plasma travelling through porous media. More so, the study of flow through porous media is intriguing due to its wide range of uses in geophysical scenarios, Magneto Hydrodynamic (MHD) fluxes, labs, businesses, and chemical and petroleum engineering. The Darcy law-based radiative thermal behavior of a magneto hydrodynamic nano fluid in a porous medium. The issue of spinning plasma with a radiative heat-loss function and FLR corrections flowing through a porous material, or Jeans instability. Thus, we conclude that judgments of the instability and stability of thermally magnetized plasma moving through porous medium heavily depend on the medium's porosity. Additionally, because to FLR's enormous relevance to astrophysics, its significance in thermal instability and gravitational instability of plasma is significant today. The significance of FLR corrections in thermal instability with various parameters has been extensively studied by scholars. The Jeans instability issue with a spinning, finitely conducting radiative plasma and FLR corrections flowing through a porous media. It is therefore obvious that FLR is an important restriction when discussing thermal instability and Jeans-gravitational instability. The aforementioned lessons have taught us that it is crucial to discuss the combined influence of rotation, FLR corrections, radiative heat-loss function, thermal conductivity, and porosity on the thermal instability since it has an impact on star formation. We therefore attempt to argue the impact of rotation, porosity, and FLR corrections on thermal instability of plasma with thermal conductivity and radiative heat-loss function while keeping in mind the significance of rotation and FLR corrections in configuration of astrophysical small and big structures.

结论

在前面提到的研究中,我们强调旋转的影响,孔隙度,FLR修正等离子体的热不稳定性,同时考虑导热和辐射热量损失函数。一般的色散关系,这是定制的可测量的物理特性的存在,是收购。色散关系是浓缩的横波传播沿着磁场的路径,并进一步支持转动轴的平行和垂直于场的路径。沿着磁场旋转轴和横波传播的模式,我们获得的两种模式。几乎不稳定模式是第一个。第二个模式提供了热模式和旋转,孔隙度、FLR调整,辐射热量损失函数的修改。我们发现存在的孔隙度、旋转、FLR修正,辐射热量损失函数,热导率变化热不稳定的状态。在non-FLR介质的情况下,发现存在旋转和孔隙度变化热不稳定性的条件,这就解释了稳定的效果。发现存在的孔隙度、旋转,和磁场变化对non-FLR热不稳定性的条件。
