Neutron stars may be much heavier than predicted by theory. This is possibly due to hyperons, i.e. poorly understood elementary particles. John Bulava aims at reconciling theory and experiment with new simulations.

Neutron stars are among the densest objects in the universe. The processes taking place inside them are a mystery to particle physics. Observation and theory don’t match. This could be due to a lack of understanding of so-called hyperons - particles that contain a unique component, namely the strange quark. They are unstable and therefore difficult to study. Professor John Bulava from Ruhr University Bochum, Germany, is using computer simulations to get to the bottom of this problem. ...
