Time-domain anomalies in solar and stellar flares
Sergey A. Belov, Dmitrii Y. Kolotkov, Akshay V. Mehta +1
The temporal morphology of flare light curves encodes the underlying flare physics, and deviations from the typical flare profile may indicate the presence of mechanisms not captur…
Entropy-mode imprints in the solar corona: non-exponential damping and phase shifts of compressive oscillations
Dmitrii Kolotkov, Sergey Belov, Mohamed Sherif
Magnetohydrodynamic (MHD) waves in coronal loops provide key seismological diagnostics through their characteristic time signatures. While fast and slow magnetoacoustic modes are r…
Spatio-temporal analysis of helioseismic quasi-biennial oscillations
Amir Hasanzadeh, Anne-Marie Broomhall, Dmitrii Kolotkov +1
Quasi-biennial oscillations (QBOs) are shorter-term periodic signals that occur alongside the dominant 11-year solar cycle. In this study, we examine the spatial and temporal evolu…
Thermodynamic Evolution of Flaring Loops with Non-local Thermal Transport
S. Belov, T. Parmenter, T. Arber +3
Hot solar coronal loops, such as flaring loops, reach temperatures where the thermal transport becomes non-local. This occurs when the mean-free-path of electrons can no longer be…
Non-local thermal transport impact on compressive waves in two-temperature coronal loops
S. A. Belov, T. Goffrey, T. D. Arber +1
Context. Observations of slow magnetoacoustic waves in solar coronal loops suggest that, in hot coronal plasma, heat conduction may be suppressed in comparison with the classical t…
