16. The neutron star matter Equation of State: a challenge for nuclear physics theory

Dr Fiorella Burgio (INFN Sezione di Catania)

26/10/2023, 14:30

Invited Speaker

I will review the recent developments in the construction of the Equation of State of hot and dense matter and its application to neutron stars observations, which have become recently a fundamental tool to constrain the properties of nuclear matter. I will discuss the main open questions in the nuclear many-body theory and its future perspectives.

26. Pions, hyperons and quark matter in neutron star mergers

Dr Andreas Bauswein (GSI Darmstadt)

26/10/2023, 15:00

Invited Speaker

We discuss recent calculations investigating the detailed impact of various "non-nucleonic" degrees of freedom in neutron star mergers. Pions are neglected in equation of state tables for merger simualtions but might actually occur in neutron star matter. We quantify their potential impact on the obseravbles of neutron star mergers. We describe a weak but potentially measurable signature of...

77. Modeling the strong-field dynamics of binary neutron star merger

Prof. Sebastiano Bernuzzi

27/10/2023, 12:30

Binary neutron star mergers (BNSM) are cosmic collisions of compact
stars associated to powerful gravitational and electromagnetic
astronomical transients. Multimessenger observations of BNSMs promise
to deliver unprecedented insights on fundamental physics questions,
including constraints on dense matter models and the production of
heavy elements. Detailed theoretical predictions...
