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…

Chromospheric Dynamics of an Umbral Flare Kernel - Based on Coordinated SUNRISE III SCIP and Domeless Solar Telescope Observations

Ayumi Asai, Satoru UeNo, Takuma Matsumoto +34

We report imaging spectroscopic observations of an M1.4 solar flare obtained during a coordinated observation between the infrared spectropolarimeter SCIP onboard the SUNRISE-III b…

Three-dimensional Magnetic Structures of Ellerman Bombs revealed by SUNRISE III/SCIP

Yusuke Kawabata, Yukio Katsukawa, Masahito Kubo +37

Ellerman bombs (EBs) are widely recognized as photospheric and chromospheric signatures of magnetic reconnection. However, the three-dimensional (3D) magnetic topology has remained…

Magnetic Field Stratification in Active-Region Plage from Ca II K and Ca II 8542 Ã Spectropolarimetry

Iñigo Juanikorena Berasategi, Ernest Alsina Ballester, Javier Trujillo Bueno +31

The study measures how the line‑of‑sight magnetic field strength changes from the photosphere to the upper chromosphere in solar active‑region plage using Ca II K and Ca II 8542 Å…
