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…
The Sunrise Chromospheric Infrared Spectro-Polarimeter SCIP: an instrument for SUNRISE III
Y. Katsukawa, J. C. del Toro Iniesta, S. K. Solanki +54
The Sunrise balloon-borne solar observatory is equipped with a one-meter aperture optical telescope, offering a unique platform for uninterrupted seeing-free observations across ul…
High-speed data processing onboard sunrise chromospheric infrared spectropolarimeter for the SUNRISE III balloon telescope
Masahito Kubo, Yukio Katsukawa, David Hernández Expósito +13
The Sunrise Chromospheric Infrared spectroPolarimeter (SCIP) has been developed for the third flight of the SUNRISE balloon-borne stratospheric solar observatory. The aim of SCIP i…
Extrapolation of Three-dimensional Magnetic Field Structure in Flare-productive Active Regions with Different Initial Conditions
Y. Kawabata, S. Inoue, T. Shimizu
The nonlinear force-free field (NLFFF) modeling has been extensively used as a tool to infer three-dimensional (3D) magnetic field structure. In this study, the dependency of the N…
Chromospheric magnetic field: A comparison of He I 10830 A observations with nonlinear force-free field extrapolation
Yusuke Kawabata, Andrés Asensio Ramos, Satoshi Inoue +1
The nonlinear force-free field (NLFFF) modeling has been extensively used to infer the three-dimensional (3D) magnetic field in the solar corona. One of the assumptions in the NLFF…
Chromospheric polarimetry through multi-line observations of the 850 nm spectral region III: Chromospheric jets driven by twisted magnetic fields
C. Quintero Noda, H. Iijima, Y. Katsukawa +11
We investigate the diagnostic potential of the spectral lines at 850 nm for understanding the magnetism of the lower atmosphere. For that purpose, we use a newly developed 3D simul…
Statistical Relation between Solar Flares and Coronal Mass Ejections with Respect to Sigmoidal Structures in Active Regions
Y. Kawabata, Y. Iida, T. Doi +3
Statistical dependencies among features of coronal mass ejections (CMEs), solar flares, and sigmoidal structures in soft-X-ray images were investigated. We applied analysis methods…
Non-potential field formation in the X-shaped quadrupole magnetic field configuration
Yusuke Kawabata, Satoshi Inoue, Toshifumi Shimizu
Some types of solar flares are observed in X-shaped quadrupolar field configuration. To understand the magnetic energy storage in such a region, we studied non-potential field form…
Chromospheric polarimetry through multi-line observations of the 850 nm spectral region
C. Quintero Noda, T. Shimizu, Y. Katsukawa +6
Future solar missions and ground-based telescopes aim to understand the magnetism of the solar chromosphere. We performed a supporting study in Quintero Noda et al. (2016) focused…
