TL;DR: The National Science Foundation's Daniel K. Inouye solar telescope (DKIST) as discussed by the authors provides the highest-resolution observations of the Sun ever achieved with a 4-m aperture.
Journal ArticleDOI
Spectropolarimetric capabilities of Ca ii 8542 Å line
C. Quintero Noda,Toshifumi Shimizu,J. de la Cruz Rodríguez,Yukio Katsukawa,Kiyoshi Ichimoto,Tetsu Anan,Yoshinori Suematsu +6 more
TL;DR: In this article, the sensitivity of the Ca II 8542 angstrom line to perturbations applied to the physical parameters of reference semi-empirical 1D model atmospheres using response functions was investigated.
Journal ArticleDOI
Chromospheric polarimetry through multiline observations of the 850-nm spectral region
C. Quintero Noda,Toshifumi Shimizu,Yukio Katsukawa,J. de la Cruz Rodríguez,Mats Carlsson,Tetsu Anan,T. Oba,Kiyoshi Ichimoto,Yoshinori Suematsu +8 more
TL;DR: In this paper, the authors performed a supporting study in Quintero Noda et al. focused on the infrared Ca (II) spectrum of the solar chromosphere and showed that the Ca(II) is a weakly magnetic field.
Journal ArticleDOI
Spicule Dynamics over a Plage Region
Tetsu Anan,Reizaburo Kitai,T. Kawate,Takuma Matsumoto,Kiyoshi Ichimoto,Kazunari Shibata,Andrew Hillier,Kenichi Otsuji,Hiroko Watanabe,Satoru Ueno,Shin'ichi Nagata,Takako T. Ishii,Hiroyuki Komori,Keisuke Nishida,Tahei Nakamura,Hiroaki Isobe,M. Hagino +16 more
TL;DR: In this paper, the authors studied spicular jets over a plage area and derived their dynamic characteristics using Hinode solar optical telescope (SOT) high-resolution images and applied the image processing method "MadMax" developed by Koutchmy et al.
Journal ArticleDOI
Shock Heating Energy of Umbral Flashes Measured with Integral Field Unit Spectroscopy
TL;DR: In this article, the authors quantified the shock heating energy of these umbral flashes using observations in the near infrared He I triplet obtained on 2014 December 7 with the SpectroPolarimetric Imager for the Energetic Sun (SPIES), which is a novel integral field unit spectrograph at the Dunn Solar Telescope.
