摘要:

基于全球平衡态的磁流体物理,对CODET模型及其对电子密度和温度的预测进行了热力学解释。热力学解释发现与模型的一致性与磁物质介质是抗磁性的,在理想的磁流体力学(MHD)的背景下。进一步指出,CODET预言了日冕电子气的多变异常指数。研究表明,这种不寻常的特征与低静止太阳日冕是一种磁物质状态的假设是一致的,该状态具有一种底层结构,该结构之前曾被描述为解释气体分子在给定温度和压力下固体表面的二维吸附过程。在我们的情况下,它是假设我们是在一个3-D类似的聚结过程,即在热力学平衡的朗缪尔非晶晶格的存在。以这种方式,介质的磁导率,非色散声速,预期的平衡时间为1.1至1.3 $R_{\odot}$,和能量密度的本构性质的定量确定为大多数的静止日冕在近太阳极小期,从2008年到2009年延长了几个月。

英文摘要:

We reach a thermodynamic interpretation of CODET model and its prediction to electrons density and temperature grounded on the physics of hydro magnetism in global equilibrium. The thermodynamic interpretation finds consistency with the model with a magneto-matter medium that is diamagnetic, in the context of ideal magnetohydrodynamics (MHD). It is further noticed that the CODET predicts a polytropic anomalous index for the electron gas of the Sun's corona. It is shown that this unusual characteristic is consistent with assuming that the low quiescent solar corona is a magneto-matter state which possesses an underlying structure that was earlier described to explain the 2-D adsorption process by a surface of a solid of molecules of a gas at a given temperature and pressure by Langmuir. In our case, it is assumed that we are in the presence of a 3-D similar coalescence process, i.e. a Langmuir amorphous lattice in thermodynamic equilibrium. In this way, constitutive properties of the medium magnetic permeability, the non-dispersive acoustic speed, the expected equilibration time for the 1.1 to 1.3$R_{\odot}$, and energy density are determined quantitatively for most of the quiescent corona in a near solar minimum that extends for several months from 2008 to 2009.
