Effects of dilute neutron matter on the neutron star crust equation of state
Guilherme Grams, Jerome Margueron
We develop a compressible liquid-drop model to describe the crust of neutron stars for which the role of the nuclear clusters, the neutron gas, and the electrons are clearly identi…
Skyrme-Hartree-Fock-Bogoliubov mass models on a 3D mesh: III. From atomic nuclei to neutron stars
Guilherme Grams, Wouter Ryssens, Guillaume Scamps +2
We present BSkG3, the latest entry in the Brussels-Skyrme-on-a-grid series of large-scale models of nuclear structure based on an energy density functional. Compared to its predece…
The mass of odd-odd nuclei in microscopic mass models
W. Ryssens, G. Scamps, G. Grams +3
Accurate estimates of the binding energy of nuclei far from stability that cannot be produced in the laboratory are crucial to our understanding of nuclear processes in astrophysic…
Progress on Brussels-Skyrme atomic mass models on a grid: stiff neutron matter equation of state
Guilherme Grams, Wouter Ryssens, Guillaume Scamps +2
We report here the current developments on the Brussels-Skyrme-on-a-Grid (BSkG) atomic mass models. In comparison with our previous models, BSkG3 improves the infinite nuclear matt…
Nuclear incompressibility and sound speed in uniform matter and finite nuclei
Guilherme Grams, Rahul Somasundaram, Jerome Margueron +1
We have extended the compressible liquid-drop model (CLDM) with a density-dependent surface term (eCLDM), which allows for a unified description of both the nuclear ground state en…
Confronting a set of Skyrme and predictions for the crust of neutron stars
Guilherme Grams, Jérôme Margueron, Rahul Somasundaram +1
With the improved accuracy of neutron star observational data, it is necessary to derive new equation of state where the crust and the core are consistently calculated within a uni…
Properties of the neutron star crust: Quantifying and correlating uncertainties with improved nuclear physics
G. Grams, R. Somasundaram, J. Margueron +1
A compressible liquid-drop model (CLDM) is used to correlate uncertainties associated with the properties of the neutron star (NS) crust with theoretical estimates of the uncertain…
Properties of neutron star crust with improved nuclear physics: Impact of chiral EFT interactions and experimental nuclear masses
Grams, G., Margueron +5
A compressible liquid-drop approach adjusted to uniform matter many-body calculations based on chiral EFT interactions and to the experimental nuclear masses is used to investigate…
Can generalized TOV equations explain neutron star macroscopic properties?
Clésio E. Mota, Guilherme Grams, Débora P. Menezes
In the quest for describing massive neutron stars with radii compatible with recent expectations, we take a different approach in the present paper and, instead of tuning the equat…
Pasta phases within the QMC model
Guilherme Grams, Alexandre M. Santos, Prafulla K. Panda +2
In this work the low density regions of nuclear and neutron star matter are studied. The search for the existence of pasta phases in this region is performed within the context of…
Preliminary EoS for core-collapse supernova simulations with the QMC model
Guilherme Grams, Alexandre M. Santos, Débora P. Menezes
In this work we present the preliminary results of a complete equation of state (EoS) for core-collapse supernova simulations. We treat uniform matter made of nucleons using the th…
