Collective Vortex Dynamics: From Isolated Vortices to their Communities
Lauren McClure, Suzana Silva, Gary Verth +2
Small-scale vortical motions in the upper solar atmosphere are abundant and occupy about 2.8% of the photosphere at any given time. Although considerable work has focused on the de…
Observing solar vortices with existing and future instrumentation. Solar Physics International Network for Swirls (SPINS) white paper (Helio)
Suzana S. A. Silva, Viktor Fedun, Gary Verth +13
Solar vortices are fundamental components of solar atmospheric dynamics, serving as natural laboratories for magnetic field twisting, energy concentration and transport, wave guida…
Solar Vortex Detection With Velocity Field Normalisation: Eliminating False Positives
Lauren McClure, Suzana Silva, Gary Verth +2
Small-scale vortices in the solar photosphere play a central role in transporting mass, energy, and momentum into the upper solar atmosphere, yet reliably detecting these structure…
Characterizing Vortex-Driven Dynamics in the Solar Atmosphere Using Information Theory
Suzana S. A. Silva, Erico Rempel, Gary Verth +2
Solar vortex regions show enhanced Poynting flux and favourable heating conditions, but how the vortices reorganize and influence their surroundings remains unclear. Here we apply…
Solar Vortices as Conduits for Magnetoacoustic Waves: Multi-Layer Coupling and Their Role in Atmospheric Heating
Suzana S. A. Silva, Ioannis Dakanalis, Luiz A. C. A. Schiavo +10
The Sun's atmosphere hosts swirling plasma structures, known as solar vortices, which have long been thought to channel wave energy into higher layers. Until now, no direct observa…
Global CME-driven oscillations in the outer solar corona
Suzana S. A. Silva, J. J. Gonzalez-Aviles, Pete Riley +8
Coronal mass ejections (CMEs) are known drivers of large-scale waves in the low corona. However, wave dynamics in the extended corona and inner heliosphere remain largely unexplore…
