A short walk through the physics of neutron stars

I Vidana - The European Physical Journal Plus, 2018 - epjplus.epj.org

introduction we present a brief historical overview of the idea of neutron stars as well as of …

Exploring robust correlations between fermionic dark matter model parameters and neutron star properties: A two-fluid perspective

P Thakur, T Malik, A Das, TK Jha, C Providência - Physical Review D, 2024 - APS
We investigate the probable existence of dark matter in the interior of neutron stars. Despite
the current state of knowledge, the observational properties of neutron stars have not …

Constraining the symmetry energy at subsaturation densities using isotope binding energy difference and neutron skin thickness

Z Zhang, LW Chen - Physics Letters B, 2013 - Elsevier
We show that the neutron skin thickness Δ rnp of heavy nuclei is uniquely fixed by the
symmetry energy density slope L (ρ) at a subsaturation cross density ρ c≈ 0.11 fm− 3 rather …

Bayesian inference of the symmetry energy and the neutron skin in and from CREX and PREX-2

Using the recent model-independent determination of the charge-weak form factor
difference Δ F CW in Ca 48 and Pb 208 by the CREX and PREX-2 collaborations together …

Core-crust transition in neutron stars: Predictivity of density developments

C Ducoin, J Margueron, C Providência, I Vidana - Physical Review C—Nuclear …, 2011 - APS
The possibility to draw links between the isospin properties of nuclei and the structure of

Symmetry energy, its density slope, and neutron-proton effective mass splitting at normal density extracted from global nucleon optical potentials

C Xu, BA Li, LW Chen - Physical Review C—Nuclear Physics, 2010 - APS
Based on the Hugenholtz–Van Hove theorem, it is shown that both the symmetry energy E
sym (ρ) and its density slope L (ρ) at normal density ρ 0 are completely determined by the …

Pulsar glitches: The crust may be enough

J Piekarewicz, FJ Fattoyev, CJ Horowitz - Physical Review C, 2014 - APS
Background: Pulsar glitches—the sudden spin-up in the rotational frequency of a neutron
star—suggest the existence of an angular-momentum reservoir confined to the inner crust of …
