Strongly interacting matter in extreme magnetic fields
Prabal Adhikari, Martin Ammon, Sidney S. Avancini +58
Magnetic fields are ubiquitous across different physical systems of current interest; from the early Universe, compact astrophysical objects and heavy-ion collisions to condensed m…
Radial Oscillations in Hybrid Stars with Slow Quark Phase Transition
Ishfaq Ahmad Rather, Kauan D. Marquez, Betânia C. Backes +2
This study investigates the radial oscillations of hybrid neutron stars, characterized by a composition of hadronic external layers and a quark matter core. Utilizing a density-dep…
Supernova Remnants with Mirror Dark Matter and Hyperons
Adamu Issifu, Prashant Thakur, Franciele M. da Silva +5
For the first time, we use relativistic mean-field (RMF) approximation with density-dependent couplings, adjusted by the DDME2 parameterization, to investigate the effects of dark…
Non-Radial Oscillation Modes in Hybrid Stars with Hyperons and Delta Baryons
Ishfaq Ahmad Rather, Kau D. Marquez, Prashant Thakur +1
We study the effects of hyperons, delta baryons, and quark matter phase transitions on -mode oscillations in neutron stars. Using the density-dependent relativistic mean-field m…
Radial Oscillations of Hybrid Stars and Neutron Stars including Delta baryons: The Effect of a Slow Quark Phase Transition
Ishfaq Ahmad Rather, Kauan D. Marquez, Betania C. Backes +2
We study radial oscillations of hybrid neutron stars composed of hadronic external layers followed by a quark matter core. We employ a density-dependent relativistic mean-field mod…
Radial Oscillations in Neutron Stars with Delta Baryons
Ishfaq A. Rather, Kauan D. Marquez, Grigoris Panotopoulos +1
We investigate the effect of baryons on the radial oscillations of neutron and hyperon stars, employing a density-dependent relativistic mean-field model. The spin- baryon…
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…
The baryon coupling scheme in an unified SU(3) and SU(6) symmetry formalism
Luiz L. Lopes, Kauan D. Marquez, Débora P. Menezes
We calculate the baryon-meson coupling constants for the spin-1/2 baryonic octet and spin-3/2 decuplet in a unified approach relying on symmetry arguments such as the fact that the…
Exploring the effects of Delta Baryons in magnetars
K. D. Marquez, M. R. Pelicer, S. Ghosh +4
Strong magnetic fields can modify the microscopic composition of matter with consequences on stellar macroscopic properties. Within this context, we study, for the first time, the…
Delta baryons in neutron stars
Kauan D. Marquez, Helena Pais, Débora P. Menezes +1
By applying a relativistic mean-field description of neutron star matter with density dependent couplings, we analyse the properties of two different matter compositions: nucleonic…
Delta Baryons in Neutron-Star Matter under Strong Magnetic Fields
Veronica Dexheimer, Kauan D. Marquez, Débora P. Menezes
In this work, we study magnetic field effects on neutron star matter containing the baryon octet and additional heavier spin 3/2 baryons (the 's). We make use of two different r…
Hadron-quark phase transition: the QCD phase diagram and stellar conversion
Clebson A. Graeff, Marcelo D. Alloy, Kauan D. Marquez +2
Different extensions of the Nambu-Jona-Lasinio model, known to satisfy expected QCD chiral symmetry aspects, are used to investigate a possible hadron-quark phase transition at zer…
Phase transition in compact stars: nucleation mechanism and -ray bursts revisited
Kauan D. Marquez, Débora P. Menezes
We have revisited the nucleation process based on the Lifshitz-Kagan theory, which is the underlying mechanism of conversion of a pulsar constituted of hadronic matter to a quark s…
