Glueballs Confinement and Cosmological Phase Transitions
Adamu Issifu, Julio C. M. Rocha, Francisco A. Brito +1
We develop a unified framework in which the dynamics of a scalar glueball field, originating from phenomenological nonperturbative QCD confinement, simultaneously governs the decon…
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…
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…
Scalarized Hot Neutron Stars Containing Hyperons and -Resonances in Different Evolution Regimes
Fahimeh Rahimi, Zeinab Rezaei, Adamu Issifu
Scalar-tensor gravity models are among the prime candidates to explain cosmic acceleration, and compact stars provide unique laboratories for testing such theories. Predictions of…
Magnetized Proto-Neutron Stars: Structure and Stability
Harsh Chandrakar, Adamu Issifu, Prashant Thakur +2
We investigate the evolution of magnetized protoneutron stars (PNSs) through four schematic stages: neutrino trapped, deleptonization, neutrino transparent, and the final cold, cat…
Rotating Proto-Neutron Stars Admixed with Mirror Dark Matter: A two fluid approach
Adamu Issifu, Andreas Konstantinou, Prashant Thakur +1
This work investigates the impact of mirror dark matter (DM) on the global properties of rotating neutron stars (NSs) across evolutionary stages, from hot, lepton-rich protoneutron…
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…
Radial and Non-Radial Oscillations of Protoneutron Stars with Hyperonic Composition
Prashant Thakur, Adamu Issifu, Ishfaq Ahmad Rather +2
This paper explores radial and non-radial oscillations of protoneutron stars (PNSs) as they evolve from hot, neutrino-rich configurations through deleptonization to cold, catalyzed…
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…
