Statistical Study of Appearance Timing of H Postflare Loops: Simple Scaling Law Based on Radiative Cooling
Takato Otsu, Ayumi Asai, Kai Ikuta +1
Recent Sun-as-a-star studies have shown that postflare loops can manifest as a secondary peak in the H light curve, suggesting that stellar postflare loops are detectable. To u…

Sun-as-a-star Analysis of the X1.6 Flare on 2023 August 5: Dynamics of Post-flare Loops in Spatially Integrated Observational Data
Takato Otsu, Ayumi Asai, Kai Ikuta +1
Post-flare loops are loop-like plasmas observed during the decay phase of solar flares, and they are expected to exist for stellar flares. However, it is unclear how post-flare loo…

A fast-filament eruption observed in the H spectral line. I. Imaging spectroscopy diagnostic
Denis P. Cabezas, Kiyoshi Ichimoto, Ayumi Asai +4
Context. Solar filament eruptions usually appear to occur in association with the sudden explosive release of magnetic energy accumulated in long-lived arched magnetic structures.…
