Magnetic Energy Powers the Corona: How We Can Understand its 3D Storage & Release
Amir Caspi, Daniel B. Seaton, Roberto Casini +12
The coronal magnetic field is the prime driver behind many as-yet unsolved mysteries: solar eruptions, coronal heating, and the solar wind, to name a few. It is, however, still poo…
Magnetic Field of Solar Dark Filaments Obtained from He I 10830 Angstrom Spectro-polarimetric Observation
Daiki Yamasaki, Yu Wei Huang, Yuki Hashimoto +4
Solar filaments are dense and cool plasma clouds in the solar corona. They are supposed to be supported in a dip of coronal magnetic field. However, the models are still under argu…
Study of Time Evolution of Thermal and Non-Thermal Emission from an M-Class Solar Flare
Shunsaku Nagasawa, Tomoko Kawate, Noriyuki Narukage +3
We conduct a wide-band X-ray spectral analysis in the energy range of 1.5-100 keV to study the time evolution of the M7.6 class flare of 2016 July 23, with the Miniature X-ray Sola…
Nowcast of an EUV dynamic spectrum during solar flares
Toshiki Kawai, Shinsuke Imada, Shohei Nishimoto +2
In addition to X-rays, extreme ultraviolet (EUV) rays radiated from solar flares can cause serious problems, such as communication failures and satellite drag. Therefore, methods f…
Estimating the temperature and density of a spicule from 100 GHz data obtained with ALMA
Masumi Shimojo, Tomoko Kawate, Takenori J. Okamoto +6
We succeeded in observing two large spicules simultaneously with the Atacama Large Millimeter/submillimeter Array (ALMA), the Interface Region Imaging Spectrograph (IRIS), and the…
Infrequent Occurrence of Significant Linear Polarization in H Solar Flares
Tomoko Kawate, Yoichiro Hanaoka
We performed statistical and event studies of linear polarization in the H line during solar flares. The statistical study revealed that, among 71 H flares analyzed, includin…
Measurement of Vector Magnetic Field in a Flare kernel with a Spectropolarimetric Observation in He I 10830 A
Tetsu Anan, Takurou Yoneya, Kiyoshi Ichimoto +5
A flare kernel associated with a C4 class flare was observed in a spectral window including the He I triplet 10830 A and Si I 10827 A with a spectropolarimeter on the Domeless Sola…
Blue wing enhancement of the chromospheric Mg II h and k lines in a solar flare
Akiko Tei, Takahito Sakaue, Takenori J. Okamoto +6
We performed coordinated observations of AR 12205, which produced a C-class flare on 2014 November 11, with the Interface Region Imaging Spectrograph (IRIS) and the Domeless Solar…
White paper of the "soft X-ray imaging spectroscopy"
Noriyuki Narukage, Shin-nosuke Ishikawa, Tomoko Kawate +2
The solar corona is full of dynamic phenomena, e.g., solar flares, micro flares in active regions, jets in coronal holes and in the polar regions, X-ray bright points in quiet regi…
UV/EUV High-Throughput Spectroscopic Telescope: A Next Generation Solar Physics Mission white paper
S. Imada, T. Shimizu, T. Kawate +2
The origin of the activity in the solar corona is a long-standing problem in solar physics. Recent satellite observations, such as Hinode, Solar Dynamics Observatory (SDO), Interfa…
Observations and simulations of the Na I D1 line profiles in an M-class solar flare
D. Kuridze, M. Mathioudakis, D. J. Christian +7
We study the temporal evolution of the Na I D1 line profiles in the M3.9 flare SOL2014-06-11T21:03 UT, using high spectral resolution observations obtained with the IBIS instrument…
The Relationship Between EUV Nonthermal Line Broadening and High-energy Particle During Solar Flare
Tomoko Kawate, Shinsuke Imada
We have studied the relationship between the location of EUV nonthermal broadening and high-energy particles during the large flares by using EUV imaging spectrometer onboard {\it…
Center-to-Limb Variation of Radio Emissions from Thermal-Rich and Thermal-Poor Solar Flares
Tomoko Kawate, Ayumi Asai, Ichimoto Kiyoshi
A statistical analysis of radio flare events was performed by using the event list of Nobeyama Radioheliograph in 1996-2009. We examined center-to-limb variations of 17GHz and 34GH…
