Spectral Observations and Modeling of a Solar White-light Flare Observed by CHASE
De-Chao Song, Jun Tian, Y. Li +11
The heating mechanisms of solar white-light flares remain unclear. We present an X1.0 white-light flare on 2022 October 2 (SOL2022-10-02T20:25) observed by the Chinese \ha\ Solar E…
The Solar Origin of an In Situ Type III Radio Burst Event
Meiqi Wang, Bin Chen, Sijie Yu +4
Solar type III radio bursts are generated by beams of energetic electrons that travel along open magnetic field lines through the corona and into interplanetary space. However, und…
Redshifting galaxies from DESI to JWST CEERS: Correction of biases and uncertainties in quantifying morphology
Si-Yue Yu, Cheng Cheng, Yue Pan +2
Observations of high-redshift galaxies with unprecedented detail have now been rendered possible with JWST. However, accurately quantifying their morphology remains uncertain due t…
The need for focused, hard X-ray investigations of the Sun
Lindsay Glesener, Albert Y. Shih, Amir Caspi +46
Understanding the nature of energetic particles in the solar atmosphere is one of the most important outstanding problems in heliophysics. Flare-accelerated particles compose a hug…
Fine structures of radio bursts from flare star AD Leo with FAST observations
Jiale Zhang, Hui Tian, Philippe Zarka +8
Radio bursts from nearby active M-dwarfs have been frequently reported and extensively studied in solar or planetary paradigms. Whereas, their sub-structures or fine structures rem…
Quantifying Energy Release in Solar Flares and Solar Eruptive Events: New Frontiers with a Next-Generation Solar Radio Facility
Bin Chen, Dale E. Gary, Sijie Yu +16
Solar flares and the often associated solar eruptive events serve as an outstanding laboratory to study the magnetic reconnection and the associated energy release and conversion p…
Radio Imaging Spectropolarimetry of CMEs and CME Progenitors
Bin Chen, Timothy S. Bastian, Sarah Gibson +8
Coronal mass ejections (CMEs) are the most important drivers of space weather. Central to most CMEs is thought to be the eruption of a bundle of highly twisted magnetic field lines…
Radio Studies of the Middle Corona: Current State and New Prospects in the Next Decade
Bin Chen, Jason E. Kooi, David B. Wexler +13
The "middle corona," defined by West et al. (2022) as the region between ~1.5-6 solar radii, is a critical transition region that connects the highly structured lower corona to the…
Multifrequency microwave imaging of weak transients from the quiet solar corona
Surajit Mondal, Bin Chen, Sijie Yu
Understanding the dynamics of the quiet solar corona is important for answering key questions including the coronal heating problem. Multiple studies have suggested small-scale mag…
Microwave Imaging of Quasi-periodic Pulsations at Flare Current Sheet
Yuankun Kou, Xin Cheng, Yulei Wang +4
Quasi-periodic pulsations (QPPs) are frequently detected in solar and stellar flares, but the underlying physical mechanisms are still to be ascertained. Here, we show microwave QP…
Numerical Modeling of Energetic Electron Acceleration, Transport, and Emission in Solar Flares: Connecting Loop-top and Footpoint Hard X-Ray Sources
Xiangliang Kong, Bin Chen, Fan Guo +8
The acceleration and transport of energetic electrons during solar flares is one of the outstanding topics in solar physics. Recent X-ray and radio imaging and spectroscopy observa…
Non-thermal Broadening of IRIS Fe XXI Lines Caused by Turbulent Plasma Flows in the Magnetic Reconnection Region During Solar Eruptions
