Introduction

Magnetohydrodynamic (MHD) waves are thought to play some role in the heating of cool, solar-like stars’ atmospheres, and acceleration of their winds. The role of acoustic (or longitudinal MHD) modes in energising stellar coronae has long been discounted, both from theoretical and observational considerations.… continue to the full article

Introduction

The structure and dynamics of the most energetic events in the Sun’s outer atmosphere such as flares, eruptions, coronal loops and coronal mass ejections are controlled by the magnetic field.… continue to the full article

Introduction

There is evidence that Type II spicules are due to magnetic reconnection [1-4], oscillatory reconnection [5,6] or more recently it was shown in [7] that spicules occur when magnetic tension is amplified and transported upward.… continue to the full article
