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…
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…
Full velocities and propagation directions of coronal mass ejections inferred from simultaneous full-disk imaging and Sun-as-a-star spectroscopic observations
Hong-peng Lu, Hui Tian, He-chao Chen +6
Coronal mass ejections (CMEs) are violent ejections of magnetized plasma from the Sun, which can trigger geomagnetic storms, endanger satellite operations and destroy electrical in…
Broadening and redward asymmetry of H line profiles observed by LAMOST during a stellar flare on an M-type star
Yuchuan Wu, Hechao Chen, Hui Tian +6
Stellar flares are characterized by sudden enhancement of electromagnetic radiation in stellar atmospheres. So far much of our understanding of stellar flares comes from photometri…
