Solar and Stellar Magnetohydrodynamics

Large amounts of matter need to be lifted into the solar atmosphere to create and sustain the massive plasma structures. New calculations reveal how this is possible. more

Sunspots excite magneto-acoustic waves; a team of researchers has now discovered the largest-scale oscillations of this kind in an intense sunspot. more

Bright, hot and surprisingly frequent – these are just some of the properties of the small campfires that Solar Orbiter has made visible. more

An analysis of 369 solar-like stars shows that solar brightness variations are extremely weak more

By combining modern data analysis techniques with stellar structure modelling for main-sequence and giant stars, researchers shed new light on stellar dynamos. more
