论文摘要
我们执行磁性水力学（MHD）模拟，以研究磁性色球中Alfven波的繁殖。我们在底部使用1.5维膨胀的通量管几何设置和横向扰动来生成Alfven波。与以前的研究相比，我们的扩展是我们包括Carlsson＆Leenaarts（2012）引入的辐射损失项。我们发现，当应用基于观察的横向波发生器时，在我们的模拟中，时间平均辐射损失曲线的空间分布与经典大气模型中的空间分布与之一致。另外，电晕中的能量大于安静区域中冠状加热所需的值。我们的研究表明，Alfven波驱动的模型有可能同时解释色圈的加热并将足够的能量运输到电晕。
We perform magnetohydrodynamic (MHD) simulations to investigate the propagation of Alfven wave in magnetic chromosphere. We use the 1.5-dimensional expanding flux tube geometry setting and transverse perturbation at the bottom to generate the Alfven wave. Compared with previous studies, our expansion is that we include the radiative loss term introduced by Carlsson & Leenaarts (2012). We find that when an observation based transverse wave generator is applied, the spatial distribution of the time-averaged radiative loss profile in our simulation is consistent with that in the classic atmospheric model. In addition, the energy flux in the corona is larger than the required value for coronal heating in the quiet region. Our study shows that the Alfven wave driven model has the potential to explain chromospheric heating and transport enough energy to the corona simultaneously.
