Neutron stars with an agnostic Dark sector: Core and Halo configurations from a two-fluid approach
Asit karan, Asim Kumar Saha, Tuhin Malik +2
The study of dark matter admixed neutron stars has the potential to advance our understanding of dark matter particle candidates. However, the large parameter space of dark matter…
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,…
Quark and hybrid stars with renormalization group improvement of NNLO perturbative QCD
Loïc Fernandez, Jean-Loïc Kneur, Marcus Benghi Pinto +3
Recently, the NNLO perturbative QCD pressure of cold and dense symmetric matter, with arbitrary quark masses, has been resummed within the renormalization-group-optimized perturbat…
Hyperonic equation of state for neutron stars: A systematic Bayesian comparison of density-dependent and non-linear relativistic mean-field models
Pedro Sanson, Tuhin Malik, Constança Providência
A systematic Bayesian inference study of the equation of state (EOS) of dense matter with strangeness is presented, extending five relativistic mean-field (RMF) models with both co…
Coupled nuclear and leptonic longitudinal collective modes in neutron star matter : a covariant Vlasov approach
Aziz Rabhi, Olfa Boukari, Sidney S. Avancini +1
A covariant relativistic approach based on the Vlasov equation is used to study collective modes in neutron-star matter. The analysis is carried out within relativistic mean-field…
Longitudinal collective modes in relativistic asymmetric magnetized nuclear matter within the covariant Vlasov approach
Aziz Rabhi, Olfa Boukari, Sidney S. Avancini +1
The neutron-proton-electron (npe) matter under strong magnetic field is studied in the context of the covariant Vlasov approach. A covariant relativistic approach based on the Vlas…
