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 ...

Recent advances in solar coronal extreme ultraviolet waves

Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences
Solar coronal extreme ultraviolet (EUV) waves are spectacular propagating disturbances in the appearance of EUV emission enhancements in the solar corona, similar to the tsunamis on the Earth. These ‘solar tsunamis’ are closely associated with various solar eruptions, from large-scale coronal mass ejections (CMEs) and solar flares to small-scale solar ...

Theoretical studies of the physics of the solar atmosphere [PDF]

Significant advances in our theoretical basis for understanding several physical processes related to dynamical phenomena on the sun were achieved. We have advanced a new model for spicules and fibrils.

Turbulent Suppression of Alfvénic Wave Resonances in Coronal Loops

The Astrophysical Journal
Alfvénic wave turbulence is a leading mechanism for explaining the heating of the solar corona and the acceleration of the solar wind. Alfvénic waves are observed to be prevalent throughout the inner corona.
