Ultra-compact twin stars with hybrid equations of state from bosonic dark matter
Ishfaq Ahmad Rather, Sarah Louisa Pitz, Jürgen Schaffner-Bielich
The properties of compact stars with a strong first-order phase transition to quark matter and with an additional fluid of self-interacting bosonic dark matter (DM) are studied. We…
The petit four of color-superconducting phases in proto-neutron star evolution
Selina Kunkel, Ishfaq Ahmad Rather, Hosein Gholami +2
At high densities and moderate temperatures, hadronic matter is expected to undergo a first-order phase transition into a color-superconducting (CSC) state. A proto-neutron star de…
As above, so below: assessing extremeness of the neutron-star equation of state based on the unstable branch
Tyler Gorda, Oleg Komoltsev, Aleksi Kurkela +1
Microscopic models of neutron-star matter have been widely used in astrophysical applications. The focus of attention has been on densities up to the maximal densities reached in s…
Signatures from pion condensation and lepton flavor asymmetries in the cosmological gravitational wave background
Osvaldo Ferreira, Eduardo S. Fraga, Jürgen Schaffner-Bielich
Large lepton flavor asymmetries at the QCD epoch could generate a pion condensation phase in the early Universe. For large enough tau lepton flavor asymmetries, the speed of sound…
Thermodynamic and transport properties of hot asymmetric nuclear matter within a chiral SU(3) model
Amruta Mishra, J. Schaffner-Bielich
We investigate the thermodynamic and transport properties in hot nuclear matter accounting for the medium modifications of the nucleons within a chiral SU(3) model including effect…
Generating ultra-compact neutron stars with bosonic dark matter
Sarah Louisa Pitz, Jürgen Schaffner-Bielich
In this work we investigate the properties of neutron stars admixed with selfinteracting scalar bosonic dark matter. The dark matter interaction is described by a generalized …
