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…
Comparison of exact and approximate MHD slow body mode solutions in photospheric waveguides
Anwar Aldhafeeri, Gary Verth, Viktor Fedun +2
In this study we explore the possibility of simplifying the modeling of magnetohydrodynamic (MHD) slow body modes observed in photospheric magnetic structure such as the umbrae of…
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…
A novel approach to identify resonant MHD wave modes in solar pores and sunspot umbrae: analysis
M. Stangalini, D. B. Jess, G. Verth +12
The umbral regions of sunspots and pores in the solar photosphere are generally dominated by ~mHz oscillations, which are due to -modes penetrating the magnetic region. In th…
