We investigate the influence of dark matter on hybrid stars. Using a two-fluid approach, where normal and dark matter components interact only gravitationally, we explore how dark matter can trigger the appearance of quark matter in neutron stars for

Thermodynamic Consistent Description of Compact Stars of Two Interacting Fluids: The Case of Neutron Stars with Higgs Portal Dark Matter

Autor: Hajkarim, Fazlollah, Schaffner-Bielich, Jürgen, Tolos, Laura

We consider a thermodynamically consistent approach for the computation of the masses, radii, and tidal deformabilities of compact stars consisting of two interacting fluids with separately conserved quantum numbers. We apply this interacting fluid a

Determining proto-neutron stars' minimal mass with chirally constrained nuclear equations of state

Autor: Kunkel, Selina, Wystub, Stephan, Schaffner-Bielich, Jürgen

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
