Global energetics of solar powerful events on 6 September 2017
Dong Li, Alexander Warmuth, Jincheng Wang +9
Solar flares and coronal mass ejections (CMEs) are thought to be the most powerful events on the Sun. They can release energy as high as 10^32 erg in tens of minutes,and could prod…
A Statistical Study of Short-period Decayless Oscillations of Coronal Loops in an Active Region
Dong Li, David M. Long
Coronal loop oscillations are common phenomena in the solar corona, which are often classified as decaying and decayless oscillations. Using the high-resolution observation measure…

In this paper, we report the multiwavelength observations of the partial filament eruption associated with a C1.2 class flare in NOAA active region 11236 on 13 June 2011. The event…
Flare Quasi-Periodic Pulsation Associated with Recurrent Jets
Dong Li, Fanpeng Shi, Haisheng Zhao +6
Quasi-periodic pulsations (QPPs), which carry time features and plasma characteristics of flare emissions, are frequently observed in light curves of solar/stellar flares. In this…

We report the observation of non-stationary Quasi-Periodic Pulsations (QPPs) in high-energy particles during the impulsive phase of an X4.8 flare on 2002 July 23 (SOL2002-07-23T00:…
Moving structures in ultraviolet bright points: observations from Solar Orbiter/EUI

Moving structures have been detected in coronal bright points and in a solar flare in active regions, which were bi-directional, symmetrical, simultaneous, and quasi-periodic (Ning…
Persistent fast kink magnetohydrodynamic waves detected in a quiescent prominence
Dong Li, Jianchao Xue, Ding Yuan +1
Small-scale, cyclic, transverse motions of plasma threads are usually seen in solar prominences, which are often interpreted as magnetohydrodynamic (MHD) waves. Here, we observed s…
