Generation of Surface Sausage Oscillations of a Current Sheet and Propagating Magnetoacoustic Waves by Impulsive Reconnection

The Astrophysical Journal
Magnetic reconnection and magnetohydrodynamic waves may well be both playing a role in coronal heating. In this paper, we simulate reconnection in the corona as a response to the convergence of opposite-polarity magnetic sources at the base of the corona.

On the Origins of Coronal Alfvénic Waves

The Astrophysical Journal Letters
Alfvénic waves are considered a key contributor to the energy flux that powers the Sun’s corona, with theoretical models demonstrating their potential to explain coronal EUV and X-ray emission and the acceleration of the solar wind.

Observation of Large-scale Kelvin–Helmholtz Instability Wave Driven by a Coronal Mass Ejection

The Astrophysical Journal Letters
The Kelvin–Helmholtz instability (KHI) can occur when there is a relative motion between two adjacent fluids. In the case of magnetized plasma, the shear velocity must exceed the local Alfvén speed for the instability to develop.

Source Materials and Heating of Alfvénic Slow and Hot Solar Wind Revealed by Heavy Ions

The Astrophysical Journal
This work quantitatively studies the differences of heavy ions among non-Alfvénic slow wind (N-ASSW), classical fast wind (FSW), and Alfvénic slow and hot wind (ASSW and AHSW) by effect size and Kolmogorov–Smirnov statistic.

Microwave Bright Points with Multiple Periodic Oscillations in the Solar Polar Coronal Hole during Solar Cycle Minimum

The Astrophysical Journal
During solar cycle minimum, polar coronal holes show a prominent radio brightening cap. The analysis of polar microwave enhanced radiation in polar coronal holes is helpful for understanding the magnetic field characteristics and the origin of the solar ...

Temporal evolution of MHD waves in solar coronal arcades

, 2021
[cat] En aquesta tesi estudiarem les oscil lacions verticals d'una arcada potencial en l'aproximaci o 0 d'un plasma quan diferents per ls de densitat s on considerats. Per un costat ens centrarem en l'evoluci o temporal d'aquest problema per tal d'analitzar l'altra cara de la moneda de les oscil lacions magnetohidrodin amiques, la qual tradicionalment ...
