Massive cold hybrid stars in a modified Polyakov-Nambu-Jona-Lasinio model
Sk Md Adil Imam, Pedro Costa, Mariana Dutra +3
We propose a modified Polyakov-loop Nambu--Jona-Lasinio (mPNJL) model in which the Polyakov potential is given by an explicit dependence on the quark chemical potential, allowing i…
Gravitational wave asteroseismology of dark matter hadronic stars
C. V. Flores, C. H. Lenzi, M. Dutra +2
The influence of the dark matter mass~() and the Fermi momentum~($k_{F}^{\dm}$) on the -mode oscillation frequency, damping time parameter, and tidal deformability of had…

In this work we study a relativistic mean-field (RMF) hadronic model, with nucleonic short-range correlations (SRC) included, coupled to dark matter (DM) through the Higgs boson. W…
Do short range correlations inhibit the appearance of the nuclear pasta?

It is well known that strongly correlated neutron-proton pairs, the short-range correlations (SRC), can modify many of the nuclear properties. In this work we have introduced, for…
Low-energy nuclear physics and global neutron star properties

We address the question of the role of low-energy nuclear physics data in constraining neutron star global properties, e.g., masses, radii, angular momentum, and tidal deformabilit…
