Merging nuclear physics experiments and astronomical observations to advance equation-of-state research

For most stars, neutron stars and black holes are their final resting places. When a supergiant star runs out of fuel, it expands and then rapidly collapses on itself. This act creates a neutron star—an object denser than ...
