Incompressible MHD modes in the thin magnetically twisted flux tube
O. K. Cheremnykh, V. Fedun, A. N. Kryshtal +1
Context. Observations have shown that twisted magnetic fields naturally occur, and indeed are omnipresent in the Sun's atmosphere. It is therefore of great theoretical interest in…
Axisymmetric Modes in Magnetic Flux Tubes with Internal and External Magnetic Twist
Ioannis Giagkiozis, Viktor Fedun, Robart Erdeliy +1
Observations suggest that twisted magnetic flux tubes are ubiquitous in the Sun's atmosphere. The main aim of this work is to advance the study of axisymmetric modes of magnetic fl…
Resonant Absorption of Axisymmetric Modes in Twisted Magnetic Flux Tubes
Ioannis Giagkiozis, Marcel Goossens, Gary Verth +2
It has been shown recently that magnetic twist and axisymmetric MHD modes are ubiquitous in the solar atmosphere and therefore, the study of resonant absorption for these modes hav…
Vortex Flows in the Solar Atmoshpere: Automated Identification and Statistical Analysis
Ioannis Giagkiozis, Viktor Fedun, Eamon Scullion +1
Aims. Due to the fundamental importance of vortices on the photosphere, in this work we aim to fully automate the process of intensity vortex identification to facilitate a more ro…
An Inside Look at Sunspot Oscillations with Higher Azimuthal Wavenumbers
David B. Jess, Tom Van Doorsselaere, Gary Verth +7
Solar chromospheric observations of sunspot umbrae offer an exceptional view of magneto-hydrodynamic wave phenomena. In recent years, a wealth of wave signatures related to propaga…
