Dark matter effects on hybrid star properties
César H. Lenzi, Mariana Dutra, Odilon Lourenço +2
In the present work we investigate the effects of dark matter (DM) on hybrid star properties. We assume that dark matter is mixed with both hadronic and quark matter and interact w…
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…
Hypermassive quark cores
Luiz L. Lopes, Carline Biesdorf, Débora P. Menezes
Using a quantum hadrodynamics (QHD) and MIT based models we construct hybrid stars within the Maxwell criteria of hadron-quark phase transition. We are able to produce a hybrid sta…
On the nature of the mass-gap object in the GW190814 event
Luiz L. Lopes, Debora P. Menezes
In this work, we make a very extensive study on the conditions that allow the mass-gap object in the GW190814 event to be faced as a degenerate star instead of a black hole. We beg…
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…
Density dependent quark mass model revisited: Thermodynamic consistency, stability windows and stellar properties
B. C. Backes, E. Hafemann, I. Marzolla +1
In this work a density dependent quark model is revisited, its thermodynamic consistency checked and the stability window for absolutely stable quark matter obtained. The hypothese…
