论文摘要
太阳芯中融合产生的几乎所有能量最终都被辐射到太阳大气中的太空中,而剩余的能量则以中微子的形式移走。因此,太阳能和辐射场之间的能量交换是大气建模的重要成分。描述这些相互作用的方程是已知的,但是它们的解决方案在计算上是如此昂贵,以至于它们只能以多维辐射MHD建模以近似形式解决。在这篇综述中,我讨论了光球,色球和电晕中气体和辐射之间的能量交换最常用的近似值。
Nearly all energy generated by fusion in the solar core is ultimately radiated away into space in the solar atmosphere, while the remaining energy is carried away in the form of neutrinos. The exchange of energy between the solar gas and the radiation field is thus an essential ingredient of atmospheric modeling. The equations describing these interactions are known, but their solution is so computationally expensive that they can only be solved in approximate form in multi-dimensional radiation-MHD modeling. In this review, I discuss the most commonly used approximations for energy exchange between gas and radiation in the photosphere, chromosphere, and corona.
