First Evidence of the Frequency Filtering of Magnetoacoustic Waves in the Flaring Star EK Dra
A. K. Srivastava, J. C. Pandey, Subhajeet Karmakar +7
Using the data obtained from XMM-Newton, we show the gradual evolution of two periodicities of ~4500 s and ~2200 s in the decay phase of the flare observed in a solar analog EK Dra…
An ultra-long and quite thin coronal loop without significant expansion
Dong Li, Ding Yuan, Marcel Goossens +5
Context. Coronal loops are the basic building blocks of the solar corona, which are related to the mass supply and heating of solar plasmas in the corona. However, their fundamenta…
The magnetohydrodynamic equations in terms of waveframe variables
Tom Van Doorsselaere, Norbert Magyar, M. Valeria Sieyra +1
Generalising the Elsasser variables, we introduce the Q-variables. These are more flexible than the Elsasser variables, because they also allow to track waves with phase speeds dif…
Uniturbulence and Alfven wave solar model
Tom Van Doorsselaere, M. Valeria Sieyra, Norbert Magyar +2
AWSOM-type models (Van der Holst et al. 2014) have been very successful in describing the solar atmosphere by incorporating the Alfven wave driving as extra contributions in the gl…
Wave pressure and energy cascade rate of kink waves computed with Elsasser variables
Tom Van Doorsselaere, Bo Li, Marcel Goossens +2
Numerical simulations have revealed a new type of turbulence of unidirectional waves in a plasma that is perpendicularly structured (Magyar et al. 2017), named uniturbulence. For t…
The effect of linear background rotational flows on magnetoacoustic modes of a photospheric magnetic flux tube
Samuel Skirvin, Viktor Fedun, Suzana Silva +4
Magnetoacoustic waves in solar magnetic flux tubes may be affected by the presence of background rotational flows. Here, we investigate the behaviour of and modes o…
