This study continues investigating the equilibrium structure of intense magnetic flux tubes, as calculated by solving the magnetostatic equation sin the thin flux tube approximation. Most significant about past studies was the inclusion of multistream radiative transfer in cylindrical geometry, and the continuous transition between radiative and convective energy transport. The flux tube's influence on the ambient medium was not taken into account, however, thus limiting previous work. This effect is important for examining the horizontal temperature variation, especially at the interface between the flux tube and external medium. In this study, the PIs will use a multidimensional treatment of radiative transfer in cylindrical geometry to include this effect.

本研究继续研究强磁通管的平衡结构，通过求解薄磁通管近似中的静磁方程来计算。 过去的研究最重要的是将多流辐射传输纳入圆柱形几何结构，以及辐射和对流能量传输之间的连续过渡。 然而，没有考虑通量管对环境介质的影响，从而限制了之前的工作。 这种效应对于检查水平温度变化非常重要，特别是在通量管和外部介质之间的界面处。 在这项研究中，PI 将使用圆柱几何中辐射传输的多维处理来包含这种效应。
