Chiral symmetry breaking and pion condensation in the early universe
Osvaldo Ferreira, Eduardo S. Fraga, Maurício Hippert +1
We determine the possible trajectories the universe may have followed in the QCD phase diagram during the QCD epoch. We focus on the roles of chiral symmetry breaking and pion cond…
Masquerading hybrid stars with dark matter
Carline Biesdorf, Jürgen Schaffner-Bielich, Laura Tolos
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…
Thermodynamic Consistent Description of Compact Stars of Two Interacting Fluids: The Case of Neutron Stars with Higgs Portal Dark Matter
Fazlollah Hajkarim, Jürgen Schaffner-Bielich, Laura Tolos
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 s…
Astrophysical constraints on color-superconducting phases in compact stars within the RG-consistent NJL model
Hosein Gholami, Ishfaq Ahmad Rather, Marco Hofmann +2
We determine parameters of the renormalization group-consistent three-flavor color-superconducting Nambu-Jona-Lasinio (NJL) model that are suited to investigate possible compact-st…
Determining the minimal mass of a proto-neutron star with chirally constrained nuclear equations of state
Selina Kunkel, Stephan Wystub, Jürgen Schaffner-Bielich
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 sh…
Hypernuclear Physics and Compact Stars
J. Schaffner-Bielich
Hypernuclear physics plays a decisive role for several features of compact star physics. I review the impact of hypernuclear potential depths, two-body hyperon-nucleon and hyperon…
