Partial filament eruptions have often been observed, however, the physical mechanisms that lead to filament splitting are not yet fully understood. In this study, we present a uniq…
A Type II Radio Burst Driven by a Blowout Jet on the Sun
Zhenyong Hou, Hui Tian, Wei Su +5
Type II radio bursts are often associated with coronal shocks that are typically driven by coronal mass ejections (CMEs) from the Sun. Here, we conduct a case study of a type II ra…
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…
Macrospicules and Their Connection to Magnetic Reconnection in the Lower Atmosphere
Yadan Duan, Yuandeng Shen, Hechao Chen +4
Solar macrospicules are beam-like cool plasma ejections of size in-between spicules and coronal jets, which can elucidate potential connections between plasma jetting activity at d…
Cross-loop propagation of a quasi-periodic extreme-ultraviolet wave train triggered by successive stretching of magnetic field structures during a solar eruption
Zheng Sun, Hui Tian, P. F. Chen +4
Solar extreme-ultraviolet (EUV) waves generally refer to large-scale disturbances propagating outward from sites of solar eruptions in EUV imaging observations. Using the recent ob…
