5#/6th-603 - Meeting Room 603 (Science Building)

Abstract:

Supernovae and neutron star mergers play a crucial role in the production of heavy elements in the universe, with the equation of state (EOS) of neutron star matter being key to understanding these phenomena. In this talk, I will present recent advancements in our understanding of the neutron star EOS, integrating insights from chiral effective field theory calculations, results from neutron skin experiments, and observations of gravitational waves. I will also discuss possible scenarios of quark-hadron phase transitions and their potential signatures the oscillation modes, which may be detectable by the third generation of gravitational wave detectors.
