Episodic Plasma Flows and Coronal Brightenings in an Arch Filament System Observed with SUNRISE III
Sergio Javier González Manrique, Juan Carlos Trelles Arjona, Christoph Kuckein +43
Emerging flux regions (EFRs) transport magnetic flux and release energy in the solar atmosphere, often hosting arch filament systems (AFSs). We present high-resolution observations…

Magnetoacoustic Portals in Quiet-Sun Fluxtubes Revealed by Chromospheric Spectropolarimetry with SUNRISE III/SCIP
Takayoshi Oba, Yukio Katsukawa, Masahito Kubo +36
Acoustic waves propagate into the chromosphere, contributing to energy transport and their dynamics. Their upward propagation is restricted to frequencies above the acoustic cutoff…
