The Study of Quasi-Periodic Pulsations in Solar and Stellar Flares with SKA
Valery M. Nakariakov, Atul Mohan, Vishal Upendran +5
An intensively studied phenomenon which is not described by the standard flare model are quasi-periodic pulsations (QPP) of the flaring emission. As analysis of the QPP phenomenon…
Decay Length of Slow Magnetoacoustic Waves in the Solar Corona using SDO/AIA and SolO/EUI
R. L. Meadowcroft, N. Narang, D. Berghmans +2
Slow magnetoacoustic waves have been observed in the solar corona for decades; yet, existing theories do not fully explain the wide range of observed decay lengths, and measurement…
A universal scaling between damping time and period of quasi-periodic pulsations from solar EUV brightenings to X-ray stellar flares
Daye Lim, Tom Van Doorsselaere, Valery M. Nakariakov +5
Recent high spatial and temporal resolution extreme-ultraviolet (EUV) imaging observations have revealed that quasi-periodic pulsations (QPPs), a ubiquitous signature of impulsive…
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…
Effect of Solar Flares on Decayless Kink Oscillations in Nearby Coronal Loops
Zhiyi Li, Valery M. Nakariakov, Ding Yuan +1
We present a statistical study of 130 solar flares (B to X class) that lack soft X-ray quasi-periodic pulsations and show no kink oscillations of nearby coronal loops visible in SD…
Nonlinear steepening of a fast magnetoacoustic wave in the vicinity of a coronal magnetic null point
Yu Zhong, Valery M. Nakariakov, Mariana Cécere +1
The interaction of a fast magnetoacoustic wave with a magnetic null point is studied in the context of the sympathetic flare phenomenon. Attention is paid to steepening the wave ca…
UK White Paper on Magnetohydrodynamic (MHD) seismology of solar and heliospheric plasmas
Valery M. Nakariakov, David B. Jess, Andrew N. Wright +6
Magnetohydrodynamic (MHD) seismology uses naturally occurring MHD waves to infer plasma properties that are otherwise hard to measure, especially magnetic field strength and topolo…
Power-law Indices of EUV Intensity Power Spectrum in Flaring Coronal Active Regions
Sihui Zhong, Dmitrii Y. Kolotkov, Valery M. Nakariakov
Solar intensity power spectra are usually characterised by coloured noise, with the spectral energy following a segmented power-law function of frequency, , ove…
