INT S@INT Seminar: "Quark matter in the cores of neutron stars"

Aleksi Kurkela, Stavanger University
Thursday, August 27, 2020 - 10:30am


Neutron stars are the densest astrophysical objects in the universe. 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, the quark matter. This naturally raises the question: does quark matter also exist inside neutron stars? In my talk, I describe how recent advancements in theory of superdense matter and in observations of neutron stars—such as the LIGO/Virgo detection of gravitational waves arising from a merger of two neutron stars—can inform us about what lies in the centers of neutron stars. I discuss how the different constraints point to the existence of quark matter in the cores of most massive neutron stars.
