Non-radial oscillation modes in hybrid stars: consequences of a mixed phase

Understand

We study the possibility of the existence of a deconfined quark matter in the core of neutron star (NS)s and its relation to non-radial oscillation modes in NSs and hybrid star (HS)s.

• We use relativistic mean field (RMF) models to describe the nuclear matter at low densities and zero temperature.
• The Nambu--Jona-Lasinio (NJL) model is used to describe the quark matter at high densities and zero temperature.
• A Gibbs construct is used to describe the hadron-quark phase transition (HQPT) at large densities.
