论文摘要
\ textbf {目的:}本文解决了长期的太阳能物理问题,即太阳能球体的加热和太阳风的起源。我们的目的是揭示在静sun中散发染色体加热和血浆流出的相关机制。 \ textbf {方法:}该方法基于一个两流体数值模型,该模型解释了热非平衡(电离/重组),质子+电子和氢原子的非绝热和非理想动力学。该模型被用于数值模拟染色体和等离子体在安静区域内流动的颗粒生成波的传播和耗散。 \ textbf {结果:}获得的结果表明,质子+电子和氢原子之间的碰撞是由血浆粘度,磁性电阻率和重组补充的氢原子导致热能释放,从而补偿了散发器中的辐射性和热损失,从而补偿了与最新数据相一致的垂直型号的大气,并在大气中保持了大气,从而使垂直的温度和周期均一致。 \ textbf {结论:}我们的模型猜想了肉芽生成的波动,等离子体流动和随后的加热的最强大,最全局的物理图片,它们形成并动态融合了太阳大气的各个层。
\textbf{Purpose:} This paper addresses long-standing solar physics problems, namely, the heating of the solar chromosphere and the origin of the solar wind. Our aim is to reveal the related mechanisms behind chromospheric heating and plasma outflows in a quiet-Sun. \textbf{Methods:} The approach is based on a two-fluid numerical model that accounts for thermal non-equilibrium (ionization/recombination), non-adiabatic, and non-ideal dynamics of protons+electrons and hydrogen atoms. The model is applied to numerically simulate the propagation and dissipation of granulation-generated waves in the chromosphere and plasma flows inside a quiet region. \textbf{Results:} The obtained results demonstrate that collisions between protons+electrons and hydrogen atoms supplemented by plasma viscosity, magnetic resistivity, and recombination lead to thermal energy release, which compensates radiative and thermal losses in the chromosphere, and sustains the atmosphere with vertical profiles of averaged temperature and periods of generated waves that are consistent with recent observational data. \textbf{Conclusion:} Our model conjectures a most robust and global physical picture of granulation-generated wave motions, plasma flows, and subsequent heating, which form and dynamically couple the various layers of the solar atmosphere.
