New insights into neutron star matter

Combining heavy-ion experiments, astrophysical observations, and nuclear theory

2022/06/10 by

An international research team has for the first time combined data from heavy-ion experiments, gravitational wave measurements and other astronomical observations using advanced theoretical modelling to more precisely constrain the properties of nuclear matter as it can be found in the interior of neutron stars. The results were published in the journal “Nature”.
