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,…
Charged black string immersed in a quintessence fluid and string cloud
Leonardo G. Barbosa, Franciele M. da Silva
We present a new static solution describing a charged black string immersed in a Kiselev-type quintessence fluid and a cloud of strings. The metric and field equations are solved f…
Rotational effects in quark stars: comparing different models
Adamu Issifu, Andreas Konstantinou, Franciele M. da Silva +1
We investigate the rotational properties of self-bound strange quark stars using two representative quark matter equations of state (EOS): the vector MIT bag model and the density-…
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…
