Effects of short-range correlations at high densities on neutron stars with and without DM content: role of the repulsive self-interaction
Odilon Lourenço, Everson H. Rodrigues, Carline Biesdorf +1
In this work, we investigate how short-range correlations affect relativistic hadronic models at high densities, with direct consequences for the structure of neutron stars, both w…
Holographic hybrid stars with slow phase transitions
M. Aleixo, C. H. Lenzi, M. Dutra +2
The - holographic model is used to describe the core of the hybrid star, composed by quark matter, while its crust is modeled from a hadronic relativistic mean field (RMF…
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…
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…
Surface and curvature tensions of relativistic models
Mariana Dutra, Odilon Lourenço, Débora P. Menezes
In the present paper, we show a simple method to obtain fittings for the surface and curvature tensions. The method uses the nuclear mass of a spherical fully ionized atom and a si…
Dark matter effects in modified teleparallel gravity
S. G. Vilhena, M. Dutra, O. Lourenço +1
This work investigates dark matter (DM) effects in compact objects in modified teleparallel gravity (MTG) in which a modification of Teleparallel Equivalent to General Relativity i…

In this work we investigate neutron stars (NS) in gravity for the case , is the Ricci scalar and the trace of the en…
Short-range correlation effects on the neutron star cooling
Lucas A. Souza, Rodrigo Negreiros, Mariana Dutra +2
Short range correlations (SRC) have been known to be an important aspect of nuclear theory for some time. Recent works have re-ignited interest on this topic, particularly due to t…
