Quasi-periodic Fast-mode Magnetosonic Wave Trains Detected by SDO/AIA and Their Correlation with Quasi-period Flare Pulsations
Abstract
Quasi-periodic fast propagating wave trains (QFPs; Liu et al. 2011, 2012) are a new phenomenon recently discovered in extreme ultraviolet (EUV) by the Atmospheric Imaging Assembly (AIA) onboard the Solar Dynamics Observatory (SDO). They are fast-mode magnetosonic waves, closely related to quasi-periodic pulsations of solar flares observed from radio to hard X-rays. QFPs usually originate from a flare and propagate at typically 500-2000 km/s within a funnel-shaped waveguide located inside a CME bubble. QFPs can potentially be used for coronal seismological diagnostics and provide critical clues to flare energy release and particle acceleration processes. We will present recent observational and numerical results of QFPs and compare them with quasi-periodic flare pulsations.
