The umbrella effect: Magnetic canopy topology modulates spatially averaged chromospheric three-minute power

Shahin Jafarzadeh, David B. Jess, Marco Stangalini +11

Three-minute (5 mHz) oscillations are a prominent signature of wave propagation in the solar chromosphere, but their measured power can vary substantially between full-disc o…

FastQSL 2: A Comprehensive Toolkit for Magnetic Connectivity Analysis

Jun Chen, Thomas Wiegelmann, Li Feng +2

We present a new version of FastQSL for locating quasi-separatrix layers (QSLs) -- regions characterized by strong magnetic connectivity gradients, preferential current buildup, an…

High-resolution observations of small-scale activity in coronal hole plumes

Ziwen Huang, L. P. Chitta, L. Teriaca +5

Plumes have been proposed to channel MHD waves and the solar wind into the heliosphere. High-speed propagating disturbances (PDs), though well detected in plumes, cannot yet be cle…

3D structures of the base of small-scale recurrent jets revealed by Solar orbiter

Xiaohong Li, Sami K. Solanki, Thomas Wiegelmann +7

Solar jets, characterized by small-scale plasma ejections along open magnetic field lines or the legs of large-scale coronal loops, play a crucial role in the dynamics of the solar…

Ion-rich acceleration during an eruptive flux rope event in a multiple null-point configuration

Melissa Pesce-Rollins, Alexander MacKinnon, Karl-Ludwig Klein +8

We report on the -ray emission above 100~MeV from the GOES M3.3 flare SOL2012-06-03. The hard X-ray (HXR) and microwave emissions have typical time profiles with a fast rise to…

Coronal magnetic field and emission properties of small-scale bright and faint loops in the quiet Sun

Maria S. Madjarska, Thomas Wiegelmann, Pascal Démoulin +1

The present study provides statistical information on the coronal magnetic field and intensity properties of small-scale bright and faint loops in the quiet Sun. We aim to quantita…
