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…
Three-dimensional Magnetic Field Structure of a Quiet-Sun Region Revealed by Sunrise III/SCIP
Masahito Kubo, Yukio Katsukawa, Yusuke Kawabata +38
The balloon-borne stratospheric solar observatory Sunrise III successfully completed 6.5 days of observations in July 2024. One of its focal-plane instruments, the Sunrise Chromosp…
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…
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…
Development of Fast and Precise Scan Mirror Mechanism for an Airborne Solar Telescope
Takayoshi Oba, Toshifumi Shimizu, Yukio Katsukawa +14
We developed a scan mirror mechanism (SMM) that enable a slit-based spectrometer or spectropolarimeter to precisely and quickly map an astronomical object. The SMM, designed to be…
Prime Focus Spectrograph (PFS) for the Subaru Telescope: Overview, recent progress, and future perspectives
Naoyuki Tamura, Naruhisa Takato, Atsushi Shimono +97
PFS (Prime Focus Spectrograph), a next generation facility instrument on the 8.2-meter Subaru Telescope, is a very wide-field, massively multiplexed, optical and near-infrared spec…
