High Resolution Spectroscopic Analysis of Chromospheric Line Evolution during an Energetic Flare on AD Leo
Younghun Oh, Seo-Won Chang, Jongchul Chae +6
Active M dwarfs exhibit frequent and energetic flares that provide a unique laboratory for studying chromospheric heating processes under extreme magnetic activity. To probe the fl…
Discovery of multi-temperature coronal mass ejection signatures from a young solar analogue
Kosuke Namekata, Kevin France, Jongchul Chae +14
Coronal mass ejections (CMEs) on the early Sun may have profoundly influenced the planetary atmospheres of early Solar System planets. Flaring young solar analogues serve as excell…
Coronal Abundance Fractionation Linked to Chromospheric Transverse MHD Waves in a Solar Active Region Observed with FISS/GST and EIS/Hinode
Kyoung-Sun Lee, Jongchul Chae, Hannah Kwak +5
Elemental abundances in the solar corona differ from those in the photosphere, with low first ionization potential (FIP) elements being enhanced, a phenomenon known as the FIP effe…
Large-amplitude transverse MHD waves prevailing in the H chromosphere of a solar quiet region revealed by MiHI integrated field spectral observations
Jongchul Chae, Michiel van Noort, Maria S. Madjarska +3
The investigation of plasma motions in the solar chromosphere is crucial for understanding the transport of mechanical energy from the interior of the Sun to the outer atmosphere a…
The Physical Nature of Spiral Wave Patterns in Sunspots
Juhyung Kang, Jongchul Chae, Valery M. Nakariakov +3
Recently, spiral wave patterns (SWPs) have been detected in 3 minute oscillations of sunspot umbrae, but the nature of this phenomenon has remained elusive. We present a theoretica…
