太阳大气地震学中的物理参数反演

Inversion of physical parameters in solar atmospheric seismology

Inigo Arregui

摘要:

磁流体动力学(MHD)波活动在太阳大气中普遍存在。磁流体地震学的目的是通过结合观测到的和理论上的磁流体波和振荡的特性来确定太阳大气磁场和等离子体结构中难以测量的物理参数。这种技术,类似于地震学或日震学,需要解决两个问题。直接问题涉及给定理论模型的波动性质的计算。反问题意味着未知的物理参数的计算,通过比较观察到的和理论的波动特性。太阳大气地震学已经成功地应用于不同的结构,如日冕环,日珥精细结构,针状物,或喷流。然而,它仍处于起步阶段。更多的还在后面。我们提出了一个概述最近的结果,特别强调在反演过程。

英文摘要:

Magnetohydrodynamic (MHD) wave activity is ubiquitous in the solar atmosphere. MHD seismology aims to determine difficult to measure physical parameters in solar atmospheric magnetic and plasma structures by a combination of observed and theoretical properties of MHD waves and oscillations. This technique, similar to seismology or helio-seismology, demands the solution of two problems. The direct problem involves the computation of wave properties of given theoretical models. The inverse problem implies the calculation of unknown physical parameters, by means of a comparison of observed and theoretical wave properties. Solar atmospheric seismology has been successfully applied to different structures such as coronal loops, prominence fine structures, spicules, or jets. However, it is still in its infancy. Far more is there to come. We present an overview of recent results, with particular emphasis in the inversion procedure.
