FAST Observations of Wave-like Structures in the Radio Dynamic Spectrum of AD Leo
Wenjie Zou, Hui Tian, Jiale Zhang +1
M-dwarf flare stars like AD Leo are laboratories for studying intense magnetic activities. The coherent radio bursts they produce are powerful probes of stellar coronal plasma and…
Radio Burst Phenomenology of AD Leonis and Associated Signatures of Propagation Effects
Jiale Zhang, Harish K. Vedantham, Joseph R. Callingham +1
We present the high-resolution radio dynamic spectra of AD Leonis (AD Leo) between 1.0 and 1.5 GHz taken by the Five-hundred-meter Aperture Spherical radio Telescope (FAST) on Dec.…
Starspots as the origin of ultrafast drifting radio bursts from an active M dwarf
Jiale Zhang, Hui Tian, Stefano Bellotti +16
Detecting coherent radio bursts from nearby M dwarfs provides opportunities for exploring their magnetic activity and interaction with orbiting exoplanets. However, it remains unce…
An Extreme Stellar Prominence Eruption Observed by LAMOST Time-Domain Spectroscopy
Lu Hong-Peng, Tian Hui, Zhang Li-Yun +6
We report the detection of an extreme stellar prominence eruption on the M dwarf LAMOST J044431.62+235627.9, observed through time-domain H spectroscopy with the Large Sky Area…
