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…
The Balloon-borne Investigation of Temperature and Speed of Electrons in the corona (BITSE): Mission Description and Preliminary Results
N. Gopalswamy, J. Newmark, S. Yashiro +16
We report on the Balloonborne Investigation of Temperature and Speed of Electrons in the corona (BITSE) mission launched recently to observe the solar corona from about 3 Rs to 15…
Toward Next Generation Solar Coronagraph: Diagnostic Coronagraph Experiment
K. -S. Cho, H. Yang, J. -O. Lee +8
Korea Astronomy and Space Science Institute (KASI) has been developing a next-generation coronagraph (NGC) in cooperation with NASA to measure the coronal electron density, tempera…
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…
Seismological determination of the Alfvén speed and plasma-beta in solar photospheric bright points
Il-Hyun Cho, Yong-Jae Moon, Valery M. Nakariakov +7
The Alfvén speed and plasma beta in photospheric bright points observed by the Broadband Filter Imager (BFI) of the Solar Optical Telescope (SOT) on board the \textit{Hinode} satel…
2D solar wind speeds from 6 to 26 solar radii in solar cycle 24 by using Fourier filtering
Il-Hyun Cho, Yong-Jae Moon, Valery M. Nakariakov +5
Measurement of the solar wind speed near the Sun is important for understanding the acceleration mechanism of the solar wind. In this study, we determine 2D solar wind speeds from…
