regions. However, their similarities and differences are not fully understood,
especially t...
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 relationship between physical quantities
(such as mass, kinetic ene...

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 eruption process with these characteristics, we
conducted a data-con...
