Quark matter cores in neutron stars

10.05.2019 14:15 – 15:15

Neutron stars are the densest astrophysical objects in our Universe. The cores of neutron stars reach densities that are as high as those realized in ultrarelativistic heavy-ion collisions where ordinary nuclear matter melts into a new phase of matter: quark matter. This naturally raises the question: does quark matter exist also inside neutron stars? In my talk, I describe how recent advancements in the theory of superdense matter and in observations of neutron stars—such as the LIGO/Virgo detection of gravitational waves arising from merger of two neutron stars—can inform us about what lies in the centers of neutron stars.
