Structure and astrophysical properties of dark energy admixed neutron stars
Juan M. Z. Pretel, Sergio B. Duarte, Mariana Dutra +1
The presence of a dark energy (DE) core, made of a Chaplygin dark fluid, is capable of influencing the diverse observable properties of neutron stars (NSs). However, there is also…
The nucleardatapy toolkit for simple access to experimental nuclear data, astrophysical observations, and theoretical predictions
Jérôme Margueron, Christian Drischler, Mariana Dutra +10
Systematic comparisons across theoretical predictions for the properties of dense matter, nuclear physics data, and astrophysical observations (also called meta-analyses) are perfo…
Asymmetric warm nuclear matter described by Gogny and Skyrme-version models
Odilon Lourenço, Mariana Dutra, Mario Centelles +1
In this work, we perform a detailed study of the thermodynamical properties of asymmetric nuclear matter at finite temperatures by means of the Gogny force, with a particular focus…
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…
Dark energy effects on realistic neutron stars
Juan M. Z. Pretel, Sergio B. Duarte, José D. V. Arbañil +2
By considering realistic equations of state (EoSs) to describe the ordinary matter of the stellar crust, in this study, we explore the effect of a dark energy core, made of Chaplyg…
Strange stars admixed with dark matter: equiparticle model in a two fluid approach
Isabella Marzola, Everson H. Rodrigues, Anderson F. Coelho +1
In this work, we explore the possible scenario of strange stars admixed with fermionic or bosonic dark matter. For the description of the ``visible'' sector, we use a specific phen…
Pseudoscalar mesons from a PNJL model at zero temperature
R. M. Aguirre, O. Lourenço
We study pseudoscalar , and meson properties, such as masses and couplings, in dense matter at zero temperature. We use a recently proposed phenomenological quark model,…
Recent astrophysical observations reproduced by a short-range correlated van der Waals-type model?
E. H. Rodrigues, M. Dutra, O. Lourenço
We perform an improvement in a van der Waals-type model by including it effects of short-range correlations (SRC). Attractive and repulsive parts of the nucleon-nucleon interaction…
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…
Critical parameters of consistent relativistic mean-field models
O. Lourenço, M. Dutra, D. P. Menezes
In the present work, the critical temperature, critical pressure and critical density, known as the critical parameters related to the liquid-gas phase transition are calculated fo…
Stellar properties and nuclear matter constraints
Mariana Dutra, Odilon Lourenço, Débora P. Menezes
We have analyzed stellar properties of the relativistic mean-field (RMF) parametrizations shown to be consistent with the recently studied constraints related to nuclear matter, pu…
CP violation and CPT invariance in B+- decays with final state interactions
I. Bediaga, T. Frederico, O. Lourenço
We show that, besides the usual short distance contribution for CP violation, final state interactions together with CPT invariance can play an important role in the recent observa…
