The minimal masses and radii of proto-neutron stars during different stages of their evolution are investigated. In our work we focus on two stages, directly after the supernova shock wave moves outwards, where neutrinos are still captured in the cor

Astrophysical constraints on color-superconducting phases in compact stars within the RG-consistent NJL model

Autor: Gholami, Hosein, Rather, Ishfaq Ahmad, Hofmann, Marco, Buballa, Michael, Schaffner-Bielich, Jürgen

We determine parameters of the renormalization group-consistent three-flavor color-superconducting Nambu-Jona-Lasinio (NJL) model that are suited to investigate possible compact-star configurations. Our goal is to provide quark-matter equations of st

Isospin symmetry is a fundamental concept in nuclear physics. Even though isospin symmetry is partially broken, it holds approximately for most nuclear systems, which makes exceptions very interesting from the nuclear structure perspective. In this f
