Spatial and Dynamical Relations between Spicules and Network Bright Points
Jeongwoo Lee, Eun-Kyung Lim, Viggo Hansteen
Spicules are among the most ubiquitous small-scale, jet-like features in the solar chromosphere and are widely believed to play a significant role in transporting mass and energy i…
Structures and properties of fan-shaped jets: H dark blobs and transparent regions
Heesu Yang, Maria S. Madjarska, EunKyung Lim +2
We investigated three fan-shaped jets observed above sunspot light bridges or nearby sunspot regions. The study aimed to explore the dynamics and physical properties of jets' featu…
Challan: Solar Full-disk Imaging-Spectroscopic Telescope using the Drift-Scanning Technique
Heesu Yang, Maria S. Madjarska, Donguk Song +7
The Challan instrument is a solar full-disk imaging spectroscopic telescope planned to be installed at three sites with a 120-degree longitudinal difference, enabling continuous 24…
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…
