Solar and Stellar Magnetohydrodynamics

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

A group of red giants discovered four years ago seems to be old and young at the same time. Scientists now prove that they are indeed old – and a result of star mergers. more
