Origin of small-scale evaporation flows deep in the chromosphere during a solar flare

L. P. Chitta, H. N. Smitha, F. A. Iglesias +29

Flares are caused by an abrupt release of magnetic energy in the solar atmosphere. Plasma heated to well over 10 MK filling the post-flare corona originates from a rapid heating an…

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…

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 +32

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…

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

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

We investigate the height variation of the line-of-sight (LOS) magnetic field in solar active-region (AR) plage from the upper photosphere to the upper chromosphere using co-spatia…

Vector Magnetic Field associated with an Active Region Filament Observed by SUNRISE III/SCIP in the Ca II 8542 Å Line

Takuma Matsumoto, Yukio Katsukawa, Masahito Kubo +38

We report high-spatial-resolution spectropolarimetric observations spatially associated with a solar filament, obtained with the SUNRISE Chromospheric Infrared spectro-Polarimeter…

Multi-line Wave Signatures in a Sunspot from Near-UV Sunrise III/SUSI Observations

Shahin Jafarzadeh, David B. Jess, Marco Stangalini +32

Magnetohydrodynamic waves redistribute energy in magnetic structures of the lower solar atmosphere, yet constraints on how wave power and dominant frequencies are organised above s…
