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…
The importance of horizontal Poynting flux in the solar photosphere
Suzana S. A. Silva, Mariarita Murabito, Shahin Jafarzadeh +4
The electromagnetic energy flux in the lower atmosphere of the Sun is a key tool to describe the energy balance of the solar atmosphere. Current investigations on energy flux in th…
New approach for analysing dynamical processes on the surface of photospheric vortex tubes
Yasir Aljohani, Viktor Fedun, Istvan Ballai +3
The majority of studies on multi-scale vortex motions employ a two-dimensional geometry by using a variety of observational and numerical data. This approach limits the understandi…
Waves in weakly ionised solar plasmas
A. Alharbi, I. Ballai, V. Fedun +1
Here we study the nature and characteristics of waves propagating in partially ionised plasmas in the weakly ionised limit, typical for the lower part of the solar atmosphere. The…
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…
