Novel data analysis techniques in coronal seismology
Sergey A. Anfinogentov, Patrick Antolin, Andrew R. Inglis +7
We review novel data analysis techniques developed or adapted for the field of coronal seismology. We focus on methods from the last ten years that were developed for extreme ultra…
Multi-wavelength quasi-periodic pulsations in a stellar superflare
Dmitrii Y. Kolotkov, Valery M. Nakariakov, Robin Holt +1
We present the first multi-wavelength simultaneous detection of QPP in a superflare (more than a thousand times stronger than known solar flares) on a cool star, in soft X-rays (SX…
The solar corona as an active medium for magnetoacoustic waves
D. Y. Kolotkov, D. I. Zavershinskii, V. M. Nakariakov
The presence and interplay of continuous cooling and heating processes maintaining the corona of the Sun at the observed one million K temperature were recently understood to have…
Common origin of quasi-periodic pulsations in microwave and decimetric solar radio bursts
Larisa Kashapova, Dmitrii Kolotkov, Elena Kupriyanova +3
We analyse quasi-periodic pulsations (QPP) detected in the microwave and decimeter radio emission of the SOL2017-09-05T07:04 solar flare, using simultaneous observations by the Sib…
Kink oscillations of coronal loops
V. M. Nakariakov, S. A. Anfinogentov, P. Antolin +13
Kink oscillations of coronal loops, i.e., standing kink waves, is one of the most studied dynamic phenomena in the solar corona. The oscillations are excited by impulsive energy re…
TESS observations of flares and quasi-periodic pulsations from low mass stars and potential impact on exoplanets
Gavin Ramsay, Dmitrii Kolotkov, J. Gerry Doyle +1
We have performed a search for flares and Quasi-Periodic Pulsations (QPPs) from low mass M dwarf stars using TESS 2 min cadence data. We find seven stars which show evidence of QPP…
The separation of ions and fluxes in nonlinear ion-acoustic waves
A. E. Dubinov, I. N. Kitayev, D. Y. Kolotkov
The multi-species plasma of natural or laboratory origin is often considered to host nonlinear ion-acoustic waves. We present calculations of ion fluxes induced by nonlinear ion-ac…
Fast magnetoacoustic wave trains: from tadpoles to boomerangs
Dmitrii Y. Kolotkov, Valery M. Nakariakov, Guy Moss +1
Rapidly propagating fast magnetoacoustic wave trains guided by field-aligned plasma non-uniformities are confidently observed in the Sun's corona. Observations at large heights sug…
Mixed properties of slow magnetoacoustic and entropy waves in a plasma with heating/cooling misbalance
D. I. Zavershinskii, D. Y. Kolotkov, D. S. Riashchikov +1
The processes of the coronal plasma heating and cooling were previously shown to significantly affect the dynamics of slow magnetoacoustic (MA) waves, causing amplification or atte…
Stellar Superflares Observed Simultaneously with Kepler and XMM-Newton
Alexey A. Kuznetsov, Dmitrii Y. Kolotkov
Solar and stellar flares are powerful events which produce intense radiation across the electromagnetic spectrum. Multiwavelength observations are highly important for understandin…
Slow-Mode Magnetoacoustic Waves in Coronal Loops
Tongjiang Wang, Leon Ofman, Ding Yuan +3
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 discover…
