The chromospheric component of coronal bright points. Coronal and chromospheric responses to magnetic-flux emergence
Maria S. Madjarska, Jongchul Chae, Fernando Moreno-Insertis +5
We investigate the chromospheric counterpart of small-scale coronal loops constituting a coronal bright point (CBP) and its response to a photospheric magnetic-flux increase accomp…
Impulsive wave excitation by rapidly changing granules
Hannah Kwak, Jongchul Chae, Maria S. Madjarska +2
It is not yet fully understood how magnetohydrodynamic waves in the interior and atmosphere of the Sun are excited. Traditionally, turbulent convection in the interior is considere…
Inference of chromospheric plasma parameters on the Sun
Jongchul Chae, Maria S. Madjarska, Hannah Kwak +1
The solar chromosphere can be observed well through strong absorption lines. We infer the physical parameters of chromospheric plasmas from these lines using a multilayer spectral…
The Application of the Filtered Backprojection Algorithm to Solar Rotational Tomography
Kyuhyoun Cho, Jongchul Chae, Ryun-Young Kwon +2
Solar rotational tomography (SRT) is an important method to reconstruct the physical parameters of the three-dimensional solar corona. Here we propose an approach to apply the filt…
Strong Blue Asymmetry in Hα line as a Preflare Activity
Kyuhyoun Cho, Jeongwoo Lee, Jongchul Chae +5
Chromospheric activities prior to solar flares provide important clues to solar flare initiation, but are as yet poorly understood. We report a significant and rapid H line broa…
Source Depth of Three-minute Umbral Oscillations
Kyuhyoun Cho, Jongchul Chae
We infer the depth of the internal sources giving rise to three-minute umbral oscillations. Recent observations of ripple-like velocity patterns of umbral oscillations supported th…
