High-Frequency Magnetohydrodynamic Waves with Substantial Energy in the Solar Polar Corona
Yuhang Gao, Hui Tian, Richard Morton +5
Using high‑cadence EUV images from Solar Orbiter, the authors detect a previously hidden population of high‑frequency kink MHD waves in solar polar coronal plumes, many with period…
A universal scaling between damping time and period of quasi-periodic pulsations from solar EUV brightenings to X-ray stellar flares
Daye Lim, Tom Van Doorsselaere, Valery M. Nakariakov +5
Recent high spatial and temporal resolution extreme-ultraviolet (EUV) imaging observations have revealed that quasi-periodic pulsations (QPPs), a ubiquitous signature of impulsive…
Accessing the fine temporal scale of EUV brightenings and their quasi-periodic pulsations: 1 second cadence observations by Solar Orbiter/EUI
Daye Lim, Tom Van Doorsselaere, Nancy Narang +7
Small scale extreme ultraviolet (EUV) transient brightenings are observationally abundant and critically important to investigate. Determining whether they share the same physical…
Stationary quasi-periodic pulsations in 20-second cadence TESS flares
Aadish Joshi, Tom Van Doorsselaere, Daye Lim +1
Context. Quasi-periodic pulsations (QPPs) are an inherent feature of solar and stellar flares. However, the mechanism behind them is debated hence it is necessary to further study…
Extreme-ultraviolet transient brightenings in the quiet-Sun corona : Closest-perihelion observations with Solar Orbiter/EUI
Nancy Narang, Cis Verbeeck, Marilena Mierla +9
The extreme-ultraviolet (EUV) brightenings identified by Solar Orbiter, commonly known as campfires, are the smallest transient brightenings detected to date outside active regions…
Quasi-periodic pulsations in extreme-ultraviolet brightenings
Daye Lim, Tom Van Doorsselaere, David Berghmans +5
Context. Extreme-ultraviolet (EUV) observations have revealed small-scale transient brightenings that may share common physical mechanisms with larger-scale solar flares. A notable…
