Studying strong phase transitions in neutron stars with gravitational waves
Katerina Chatziioannou, Sophia Han
The composition of neutron stars at the extreme densities reached in their cores is currently unknown. Besides nuclear matter of normal neutrons and protons, the cores of neutron s…
Treating quarks within neutron stars
Sophia Han, M. A. A. Mamun, S. Lalit +2
Neutron star interiors provide the opportunity to probe properties of cold dense matter in the QCD phase diagram. Utilizing models of dense matter in accord with nuclear systematic…
Observability of sharp phase transitions in neutron stars
Sophia Han
With central densities as high as 5-10 times the nuclear saturation density, neutron stars exhibit extreme conditions that cannot be observed elsewhere. They are ideal astrophysica…
Signatures for quark matter from multi-messenger observations
Mark G. Alford, Sophia Han, Kai Schwenzer
We review the prospects for detecting quark matter in neutron star cores. We survey the proposed signatures and emphasize the importance of data from neutron star mergers, which pr…
