A self-consistent single-fluid framework for neutron stars admixed with mirror dark matter
Adamu Issifu, Constança Providência, Franciele M. da Silva +2
We develop a self-consistent framework based on a contact vector current-current interaction that couples the chemical potentials of both sectors through mutual mean-field shifts,…
Dark Matter Heating in Evolving Proto-Neutron Stars: A Two-Fluid Approach
Adamu Issifu, Prashant Thakur, Davood Rafiei Karkevandi +4
Neutron stars (NSs) provide a unique laboratory to probe dark matter (DM) through its gravitational imprint on stellar evolution. We use a two-fluid framework with non-annihilating…
Proto-neutron Stars with Dark Matter Admixture: A Single-Fluid Approach
Adamu Issifu, Débora P. Menezes, Tobias Frederico
This work investigates the impact of dark matter (DM) on the microscopic and macroscopic properties of proto-neutron stars (PNSs). We employ a single-fluid framework in which DM in…
Hyperons and 's in rotating protoneutron stars: Local properties
Franciele M. da Silva, Adamu Issifu, Luis C. N. Santos +2
The structural evolution of rotating protoneutron stars encodes essential information about their observable signatures, while microscopic properties provide complementary knowledg…
Hyperons and 's in rotating protoneutron stars: Global properties
Franciele M. da Silva, Adamu Issifu, Luis C. N. Santos +2
Rotation plays an important role in the evolution of most types of stars, in particular, it can have a strong influence on the evolution of a newly born proto-neutron star. In this…
Strongly Interacting Quark Matter in Massive Quark Stars
Adamu Issifu, Franciele M. da Silva, Luis C. N. Santos +2
This paper investigates the properties of strongly coupled matter at high baryon densities (\(Ï_B\)) in quark stars (QSs). The QS model is based on the density-dependent quark mas…
