Unified Relationship between Cold Plasma Ejections and Flare Energies Ranging from Solar Microflares to Giant Stellar Flares
Yuji Kotani, Kazunari Shibata, Takako T. Ishii +4
We often find spectral signatures of chromospheric cold plasma ejections accompanied by flares in a wide range of spatial scales in the solar and stellar atmospheres. However, the…
A Data-constrained Magnetohydrodynamic Simulation of the X1.0 Solar Flare of 2021 October 28
Daiki Yamasaki, Satoshi Inoue, Yumi Bamba +2
The solar active region NOAA 12887 produced a strong X1.0 flare on 2021 October 28, which exhibits X-shaped flare ribbons and a circle-shaped erupting filament. To understand the e…
Polarization calibration of the Tandem Etalon Magnetograph of the Solar Magnetic Activity Research Telescope at Hida Observatory
Daiki Yamasaki, Shin'ichi Nagata, Kiyoshi Ichimoto
The Tandem Etalon Magnetograph (TEM) is one of the instruments of the Solar Magnetic Activity Research Telescope of Hida Observatory. The TEM is a partial disk (320" x240") filter…
