Modelling MHD slow body modes in solar pores and sunspot umbrae with light bridges.

在这个项目中，Aldhafeeri等人的近似。(APJ，2022)为了简化MHD慢体模式的数值建模，将使用隐式重新启动的Arnoldi方法来计算具有光桥的气孔和太阳黑子黑子的本征模式。该模型将充分考虑观测到的磁波导截面形状的不规则性，并允许背景磁场强度、压力、密度和温度在光球面内变化，以捕捉到真实的光桥结构。这项研究是最及时的，因为4米高的丹尼尔·K·井上太阳望远镜现在已经完全投入使用，这是有史以来建造的最强大的太阳望远镜。

In this project the approximation of Aldhafeeri et al. (ApJ, 2022) to simplify the numerical modelling of MHD slow body modes will be used to calculate the eigenmodes of pores and sunspot umbrae with light bridges using using an implicitly restarted Arnoldi method. The modelling will fully take into account the irregular cross-sectional shape of observed magnetic waveguides and allow the background magnetic field strength, pressure, density and temperature to vary in the plane of the photosphere to capture the realstic structure of light bridges. This research is most timely due to now fully operational status of the 4m Daniel K. Inouye Solar Telescope, the most powerful solar telescope ever built.
