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…
Definability of Hausdorff Limits for Lipschitz Cells in O-minimal Structures
Xiaoduo Wang
We study Hausdorff limits of definable families over arbitrary models of o-minimal expansions of real closed fields. Over the real field, van den Dries proved that Hausdorff limits…
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…
Expanding magnetic canopy structure and parasitic polarities in a quiet-Sun network element observed by Sunrise III/SCIP
Ryan J. Campbell, Carlos Quintero Noda, Mihalis Mathioudakis +44
We present high-resolution multi-line spectropolarimetric observations of a quiet-Sun network element obtained with the {\sc Sunrise~iii} Chromospheric Infrared SpectroPolarimeter.…
Horizontal Magnetic Fields Dominate the Quiet Sun Internetwork in Sunrise III Observations. Evidence from Traditional and Transformer-Based Inversions
Ryan J. Campbell, Carlos Quintero Noda, Manuel Collados +41
The relative prevalence of horizontal and vertical magnetic fields in the quiet-Sun internetwork remains debated, owing to the weak linear polarisation signals that make the inferr…
Three-dimensional Magnetic Field Structure of a Quiet-Sun Region Revealed by Sunrise III/SCIP
Masahito Kubo, Yukio Katsukawa, Yusuke Kawabata +38
The paper presents high‑precision spectropolarimetric observations of a quiet‑Sun region using the Sunrise III/SCIP instrument, revealing narrow, thread‑like chromospheric magnetic…
