Trace-anomaly decomposition and universal dark matter scaling in compact stars
Adamu Issifu, Constança Providência, Tobias Frederico
We investigate how dark matter (DM) admixture modifies the conformal properties and phase structure of dense neutron-star matter within a self-consistent single-fluid framework, wi…
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…
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 (\(ρ_B\)) in quark stars (QSs). The QS model is based on the density-dependent quark mass…
Proto-neutron stars with quark cores
Adamu Issifu, Débora P. Menezes, Zeinab Rezaei +1
This work investigates the evolution of proto-neutron stars (PNSs) from birth as neutrino-rich objects to maturity as cold-catalyzed neutrino-poor objects with nucleonic and non-nu…
Proto-strange quark stars from density-dependent quark mass model
Adamu Issifu, Franciele M. da Silva, Débora P. Menezes
In this paper, we investigate the evolution of strange quark stars (SQS) from birth as proto-strange quark stars to maturity as stable SQSs at a zero temperature. We assume that se…
A Bayesian study of quark models in view of recent astrophysical constraints
Franciele M. da Silva, Adamu Issifu, Luiz L. Lopes +2
In this work, we perform a comparative analysis between the density-dependent quark model and the vector MIT bag model using Bayesian analysis. We use the equations of state genera…
Hybrid Stars Built with Density Dependent Models
A. Issifu, F. M. da Silva, D. P. Menezes
Using a density dependent quark model and a relativistic model within the mean-field approximation for hadrons with density dependent meson-baryon couplings, we construct, for the…
Exotic Baryons in Hot Neutron Stars
Adamu Issifu, Kauan D. Marquez, Mateus R. Pelicer +1
We study the nuclear isentropic equation of state for a stellar matter composed of nucleons, hyperons, and -resonances. We investigate different snapshots of the evolution of a…
