Nuclear matter properties from local chiral interactions with isobar intermediate states
Domenico Logoteta, Ignazio Bombaci, Alejandro Kievsky
Using two-nucleon and three-nucleon interactions derived in the framework of chiral perturbation theory (ChPT) with and without the explicit isobar contributions, we calculate…
Fast spinning strange stars: possible ways to constrain interacting quark matter parameters
Sudip Bhattacharyya, Ignazio Bombaci, Domenico Logoteta +1
For a set of equation of state (EoS) models involving interacting strange quark matter, characterized by an effective bag constant (B_eff) and a perturbative QCD corrections term (…
The Hyperon Puzzle in Neutron Stars
Ignazio Bombaci
The so called "hyperon puzzle", i.e. the difficulty to reconcile the measured masses of neutron stars (NSs) with the presence of hyperons in their interiors, is one of the hot topi…
Quark matter nucleation in neutron stars and astrophysical implications
Ignazio Bombaci, Domenico Logoteta, Isaac Vidana +1
A phase of strong interacting matter with deconfined quarks is expected in the core of massive neutron stars. We investigate the quark deconfinement phase transition in cold (T = 0…
