Prominences are intriguing, but poorly understood, magnetic structures of the solar corona. The dynamics of solar prominences has been the subject of a large number of studies, and of particular interest is the study of prominence oscillations. Ground- and space-based observations have confirmed the presence of oscillatory motions in prominences and they have been interpreted in terms of magnetohydrodynamic waves. This interpretation opens the door to perform prominence seismology, whose main aim is to determine physical parameters in magnetic and plasma structures (prominences) that are difficult to measure by direct means. Here, we review the observational information gathered about prominence oscillations as well as the theoretical models developed to interpret small and large amplitude oscillations and their temporal and spatial attenuation. Finally, several prominence seismology applications are presented.

日珥振荡
日珥是日冕的磁性结构,虽然很有趣,但人们却知之甚少。太阳日珥的动力学一直是大量研究的主题,特别令人感兴趣的是日珥振荡的研究。地面和太空观测已证实日珥中存在振荡运动,并用磁流体动力波对其进行了解释。这种解释为进行日珥地震学打开了大门,其主要目的是确定难以通过直接方法测量的磁和等离子体结构(日珥)中的物理参数。在这里,我们回顾了收集的有关突出振荡的观测信息,以及为解释小振幅和大幅度振荡及其时间和空间衰减而开发的理论模型。最后,介绍了几个重要的地震学应用。
