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…

Time evolution of white-light flare accompanied by probable postflare loops on M-type dwarf EV Lacertae
Shinnosuke Ichihara, Daisaku Nogami, Kosuke Namekata +6
White-light flares are explosive phenomena accompanied by brightening of continuum from near-ultraviolet to optical, which occur on the Sun and stars. In order to investigate the m…

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…
