Phase-drifting with emitting plasma temperature in the quasi-periodic pulsations of an X-class solar flare
Libo Fu, Valery M. Nakariakov, Ding Yuan +3
Recent multi-wavelength observations of solar flares have provided new constraints on the physical origin of quasi-periodic pulsations (QPPs). In an X-class flare, we detect a shor…

Chromospheric resonator model for sunspot revealed by multi-height observation of umbral wave
Kartika Sangal, A. K. Srivastava, Libo Fu +3
Sunspots are transient, magnetically intense features that host oscillations linked to magnetohydrodynamic (MHD) waves. These waves may contribute to plasma heating and drive mass…

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…
