The neutron star inner crust: an empirical essay
Luiz L. Lopes
In this work we study how the small contribution of the inner crust to the total equation of state (EoS) of a neutron star affects its mass-radius relation, focusing on the canonic…
Modified MIT Bag Models -- part II: QCD phase diagram and hot quark stars
Luiz L. Lopes, Carline Biesdorf, K. D. Marquez +1
In the present work we use the modified versions of the MIT bag model, on which both a vector field and a self-interacting term are introduced, to obtain hot quark matter and to in…
Modified MIT bag Models -- part I: Thermodynamic consistency, stability windows and symmetry group
Luiz L. Lopes, Carline Biesdorf, Débora P. Menezes
In this work we study different variations of the MIT bag model. We start with the so called non-ideal bag model and discuss it in detail. Then we implement a vector interaction in…
Broken SU(6) symmetry and massive hybrid stars
Luiz L. Lopes, Debora P. Menezes
In this work we revisit the quantum hadrodynamics (QHD) formalism to investigate hyperonic and hybrid stars with hyperon-meson couplings fixed via broken SU(6) group, in favor of a…
Role of vector channel in different classes of (non) magnetized neutron stars
Luiz L. Lopes, Debora P. Menezes
We study how the magnetic field and non-standard vector channels affect hadronic, quarkionic and hybrid stars. In the hadronic phase, we use the QHD model, within its standard $σωρ…
Gravitational Wave Signatures of Highly Magnetized Neutron Stars
Cesar V. Flores, Luiz L. Lopes, Luis B. Castro +1
Motivated by the recent gravitational wave detection by the LIGO-VIRGO observatories, we study the Love number and dimensionless tidal polarizability of highly magnetized stars. We…
