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…
Detection of Flare-induced Plasma Flows in the Corona of EV Lac with X-ray Spectroscopy
Hechao Chen, Hui Tian, Hao Li +5
Stellar flares are characterized by sudden enhancement of electromagnetic radiation from the atmospheres of stars. Compared to their solar counterparts, our knowledge on the corona…
Possible detection of coronal mass ejections on late-type main-sequence stars in LAMOST medium-resolution spectra
Hong-peng Lu, Hui Tian, Li-yun Zhang +9
Context. Stellar coronal mass ejections (CMEs) are the primary driver of the exoplanetary space weather and they could affect the habitability of exoplanets. However, detections of…
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…
Chromospheric activity on the late-type star V1355 Ori using Lijiang 1.8-m and 2.4-m telescopes
Qing-Feng Pi, Li-Yun Zhang, Liang Chang +4
We obtained new high-resolution spectra using the Lijiang 1.8-m and 2.4-m telescopes to investigate the chromospheric activities of V1355 Ori as indicated in the behaviors of Ca ii…
