Quasi-periodic pulsations in solar and stellar flares: a review of underpinning physical mechanisms and their predicted observational signatures

IV Zimovets, JA McLaughlin, AK Srivastava… - Space Science …, 2021 - Springer
The phenomenon of quasi-periodic pulsations (QPPs) in solar and stellar flares has been
known for over 50 years and significant progress has been made in this research area. It has …

Slow-mode magnetoacoustic waves in coronal loops

T Wang, L Ofman, D Yuan, F Reale, DY Kolotkov… - Space Science …, 2021 - Springer
Rapidly decaying long-period oscillations often occur in hot coronal loops of active regions
associated with small (or micro-) flares. This kind of wave activity was first discovered with …

Detection of flare multiperiodic pulsations in mid-ultraviolet Balmer continuum, Lyα, hard X-ray, and radio emissions simultaneously

D Li, M Ge, M Dominique, H Zhao, G Li… - The Astrophysical …, 2021 - iopscience.iop.org
Abstract Quasi-periodic pulsations (QPPs), which usually appear as temporal pulsations of
the total flux, are frequently detected in the light curves of solar/stellar flares. In this study, we …

Flare quasi-periodic pulsation associated with recurrent jets

D Li, F Shi, H Zhao, S Xiong, L Song… - Frontiers in Astronomy …, 2022 - frontiersin.org
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 study, we …

high-resolution imaging/spectroscopic observations provided by the Solar Dynamics …

Recurrent narrow quasiperiodic fast-propagating wave trains excited by the intermittent energy release in the accompanying solar flare

X Zhou, Y Shen, H Liang, Z Qu, Y Duan… - The Astrophysical …, 2022 - iopscience.iop.org
About the driven mechanisms of the quasiperiodic fast-propagating (QFP) wave trains, there
exist two dominant competing physical explanations: they are associated with the flaring …

Statistical study of GOES X-ray quasi-periodic pulsations in solar flares

LA Hayes, AR Inglis, S Christe, B Dennis… - The Astrophysical …, 2020 - iopscience.iop.org
Small-amplitude quasi-periodic pulsations (QPPs) detected in soft X-ray emission are
commonplace in many flares. To date, the underpinning processes resulting in the QPPs are …

Detections of multi-periodic oscillations during a circular ribbon flare

Z Ning, Y Wang, Z Hong, D Li - Solar Physics, 2022 - Springer
We present the analysis of three kinds of oscillating behavior using multi-wavelength
observations of the 10 November 2013 (SOL2013-11-10T05: 14) circular-ribbon flare. This …

A blueprint of state-of-the-art techniques for detecting quasi-periodic pulsations in solar and stellar flares

AM Broomhall, JRA Davenport, LA Hayes… - The Astrophysical …, 2019 - iopscience.iop.org
Quasi-periodic pulsations (QPPs) appear to be a common feature observed in the light
curves of both solar and stellar flares. However, their quasi-periodic nature, along with the …
