They're some of the densest objects in the universe, with nutty internal physics
NASA’s Goddard Space Flight Center/Conceptual Image Lab“What we have shown, by constructing millions of equation of state models , is that maximally massive neutron stars have a lower sound speed in the core region than in their outer layers,” said Christian Ecker, an astrophysicist at Goethe University, in an email to Gizmodo.
“This hints to some material change in their cores, like for example a transition from baryonic to quark matter,” Ecker added.The researchers also found that all neutron stars are probably about 7.46 miles across, regardless of their mass. That measurement is less than half that of a that the typical neutron star was about 13.6 miles across. Despite that size, the average neutron star mass is aroundWhile the findings offer some insight about the diversity of neutron stars in terms of their consistency, the researchers did not investigate the stars’ ingredients or how they fit together.
