By combining modern data analysis techniques with stellar structure modelling researchers shed new light on stellar dynamos.  more

Shaking up Tech event brought hundreds of Finnish female students together to explore technology.  more

MPS-scientist Maarit Käpylä receives a Consolidator Grant from the European Research Commission to conduct the project "Building up a Unified Theory of Stellar Dynamos (UniSDyn)". more

Nigul Olspert, M.Sc., will defend the dissertation "From periodic to cyclic processes in stellar magnetic activity research: time series analysis methods and their applications" on Friday 16 November at 12 noon at the Aalto University School of Science, lecture hall AS1, Maarintie 8, Espoo.  more

The existence of "activity branches", that is stellar cycles clustering in groups that show linear dependencies as function of rotation, has been debated for years. Such dependencies have crucial implications on how to explain stellar magnetism in terms of dynamo theory. In this study we applied novel time series analysis techniques to one of the longest stellar activity database. more

Stellar magnetic activity level and rotation are strongly connected. We studied the effect of increasing rotation rate on solar-like stars using magnetohydrodynamic simulations of stars with outer convective envelopes. At around 1.8 times the solar rotation rate, .... more
