High-Frequency Magnetohydrodynamic Waves with Substantial Energy in the Solar Polar Corona
Yuhang Gao, Hui Tian, Richard Morton +5
The acceleration and heating of the fast solar wind remain long-standing challenges in space physics. One type of leading theoretical models requires high-frequency magnetohydrodyn…
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…
Propagating Kink Waves in Chromospheric Jet-like Structures and Coronal Plumelets
Youqian Qi, Mingzhe Guo, Zhenghua Huang +5
Coronal plumes and chromospheric jet-like structures are believed to be highly dynamic. We report the first direct observations of a propagating kink wave in a chromospheric jet-li…
Co-existence of longitudinal and transverse oscillations in polar plumes observed with Solar Orbiter/EUI
Upasna Baweja, Vaibhav Pant, S. Krishna Prasad +6
Magnetohydrodynamic (MHD) waves play a key role in heating the solar corona and driving the solar wind. Recent observations have shown the presence of slow magneto-acoustic and Alf…
Understanding the magnetic field and plasma- along umbral fan loops traced using 3-min slow waves
Ananya Rawat, Girjesh Gupta, Tom Van Doorsselaere +2
The plasma- is an important fundamental physical quantity in solar plasma physics, which determines the dominating process in the solar atmosphere, i.e., magnetic or thermodynam…
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…
Reconnection nanojets in an erupting solar filament with unprecedented high speeds
Yuhang Gao, Hui Tian, David Berghmans +4
Solar nanojets are small-scale jets generated by component magnetic reconnection, characterized by collimated plasma motion perpendicular to the reconnecting magnetic field lines.…
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…
