32. Equation of state of dense matter for application to binary neutron star mergers

Domenico Logoteta

11/10/2023, 16:50

I will review the various ways of deriving an equation of state (EOS) of dense matter both at zero and finite temperature, according to the possible presence of exotic degrees of freedom like hyperons and deconfined quarks. I will then discuss the need for an accurate knowledge of such EOS in order to describe astrophysical systems of actual interest like binary neutron star mergers and...

15. Neutron star properties from gravitational-wave observations of r-modes and post-merger events

Gravitational wave events involving neutron stars provide interesting information of their interiors. In this talk I will not focus on the compact binary inspirals (GW170817-type events), related to the measurements of the tidal deformability of the components, but present instead other types of observations expected in the future: r-modes from rotating neutron stars, as well as the signals...

16. Effect of composition fluctuations in quark nucleation

Mirco Guerrini (Istituto Nazionale di Fisica Nucleare)

At the typical conditions of compact objects and related phenomena, exotic degrees of freedom such as free quarks are expected. The deconfinement of quarks in hadronic matter begins after the first seed of quark matter is created. This process is called nucleation, which occurs by local thermal or quantum fluctuations when the hadronic phase is metastable. I will initially present the...

2. Glitches in rotating supersolids

Glitches, spin-up events in neutron stars, are of prime interest as they reveal properties of nuclear
matter at subnuclear densities. We numerically investigate the glitch mechanism using analogies
between neutron stars and magnetic dipolar gases in the supersolid phase. In rotating neutron stars,
glitches are believed to occur when many superfluid vortices unpin from the interior,...
