MHS sunspot model from deep sub-photospheric to chromospheric layers
摘要:
为了了解磁场对波的传播特性的影响,从不同的当地日震学技术,波的正演模拟是必需的。这类计算需要一个磁流体静力平衡的模型作为初始大气来传播振荡,本文提供了一种构造这种平衡模型的方法,该模型适用于人工日震数据的模拟。该方法结合了自相似解和电流分布模型的优点。通过对磁流体静力学方程组的数值积分,建立了一套从光球层到色球层的模型。
英文摘要:
In order to understand the influence of magnetic fields on the propagation properties of waves, as derived from different local helioseismology techniques, forward modeling of waves is required. Such calculations need a model in magnetohydrostatic equilibrium as initial atmosphere to propagate oscillations through it. We provide a method to construct such a model in equilibrium for a wide range of parameters to be used for simulations of artificial helioseismologic data. The method combine the advantages of self-similar solutions and current-distributed models. A set of models is developed by numerical integration of magnetohydrostatic equations from the sub-photospheric to chromospheric layers.
