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…
Sun-as-a-star Analyses of Various Solar Active Events Using H Spectral Images Taken by SMART/SDDI
Takato Otsu, Ayumi Asai, Kiyoshi Ichimoto +2
Sun-as-a-star analyses, in which observational data is spatially integrated, are useful for interpreting stellar data. For future applications to stellar observations, we performed…
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…
Sun-as-a-star Analysis of H Spectra of a Solar Flare Observed by SMART/SDDI: Time Evolution of Red Asymmetry and Line Broadening
Kosuke Namekata, Kiyoshi Ichimoto, Takako T. Ishii +1
Stellar flares sometimes show red/blue asymmetries of H line, which can indicate chromospheric dynamics and prominence activations. However, the origin of asymmetries is not com…
