The temporal and spatial evolution of MHD wave modes in sunspots
A. B. Albidah, V. Fedun, A. A. Aldhafeeri +8
Through their lifetime sunspots undergo a change in their area and shape and, as they decay, they fragment into smaller structures. Here, for the first time we analyze the spatial…
Magnetohydrodynamic wave mode identification in circular and elliptical sunspot umbrae: evidence for high order modes
A. B. Albidah, V. Fedun, A. A. Aldhafeeri +7
In this paper we provide clear direct evidence of multiple concurrent higher order magnetohydrodynamic (MHD) modes in circular and elliptical sunspots by applying both Proper Ortho…
Proper Orthogonal and Dynamic Mode Decomposition of Sunspot Data
A. B. Albidah, W. Brevis, V. Fedun +5
High resolution solar observations show the complex structure of the magnetohydrodynamic (MHD) wave motion. We apply the techniques of POD and DMD to identify the dominant MHD wave…
