Double-periodic pulsations simultaneously detected in mid-infrared and hard X-ray emissions during an X1.5 flare
Dong Li, Yuyang Ye, Xianyong Bai +1
Quasi-periodic pulsations (QPPs) have been observed in a broad electromagnetic spectrum, encompassing radio, ultraviolet, white light, X-rays, and Gama-rays. Yet, flare-associated…
Detecting fast-variation pulsations in solar hard X-ray and radio emissions
Dong Li
Quasi-periodic pulsations (QPPs) at sub-second periods are frequently detected in the time series of X-rays during stellar flares. However, such rapid pulsations are rarely reporte…
Exploring the origin of multi-periodic pulsations during a white-light flare
Dong Li, Ding Yuan, Jingye Yan +9
We explored the quasi-periodic pulsations (QPPs) at multiple periods during an X4.0 flare on 2024 May 10 (SOL2024-05-10T06:27), which occurred in the complex active region of NOAA…
Localizing short-period pulsations in hard X-rays and Gamma-rays during an X9.0 flare
Dong Li
The feature of quasi-periodic pulsations (QPPs) is frequently observed in the light curve of solar and stellar flares. In this letter, we investigated the QPP at a shorter period i…
