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…

A Markov-Chain-Monte-Carlo-based Hybrid Noise Inference for Continuous Wavelet Power Spectra: with Applications to Solar and Stellar Oscillatory Signals
Song Feng, Lin Li, Ding Yuan
Detecting oscillations in solar and stellar time series is complicated by non-stationary red noise and evolving background emission. Methods based on detrending and AR(1)-based wav…
