Analytical representations of unified equations of state for neutron-star matter

AY Potekhin, AF Fantina, N Chamel… - Astronomy & …, 2013 - aanda.org
Context. An equation of state (EoS) of dense nuclear matter is a prerequisite for studies of

Microscopic nuclear equation of state with three-body forces and neutron star structure

M Baldo, I Bombaci, GF Burgio - arXiv preprint astro-ph/9707277, 1997 - arxiv.org
We calculate static properties of non-rotating neutron stars (NS's) using a microscopic
equation of state (EOS) for asymmetric nuclear matter, derived from the Brueckner-Bethe …

Analytical representations of unified equations of state of neutron-star matter

P Haensel, AY Potekhin - Astronomy & Astrophysics, 2004 - aanda.org
Analytical representations are derived for two equations of state (EOSs) of neutron-star
matter: FPS and SLy. Each of these EOSs is unified, that is, it describes the crust and the …

Neutron star properties and the equation of state for the core

JL Zdunik, M Fortin, P Haensel - Astronomy & Astrophysics, 2017 - aanda.org
Context. Few unified equations of state for neutron star matter, in which core and crust are
described using the same nuclear model, are available. However the use of non-unified …

Equation of state constraints for the cold dense matter inside neutron stars using the cooling tail method

J Nättilä, AW Steiner, JJE Kajava… - Astronomy & …, 2016 - aanda.org
The cooling phase of thermonuclear (type-I) X-ray bursts can be used to constrain neutron
star (NS) compactness by comparing the observed cooling tracks of bursts to accurate …

Unified equations of state for cold non-accreting neutron stars with Brussels–Montreal functionals–I. Role of symmetry energy

Neutron star properties with unified equations of state of dense matter

AF Fantina, N Chamel, JM Pearson… - Astronomy & astrophysics, 2013 - aanda.org
Aims. In this paper, we study the global properties of neutron stars (NSs), as predicted by the
Brussels-Montreal equations of state (EoSs). These EoSs, which provide a unified …

Neutron star radii and crusts: Uncertainties and unified equations of state

M Fortin, C Providência, AR Raduta, F Gulminelli… - Physical Review C, 2016 - APS
The uncertainties in neutron star radii and crust properties due to our limited knowledge of
the equation of state are quantitatively analyzed. We first demonstrate the importance of a …

Mass and radius formulas for low-mass neutron stars

H Sotani, K Iida, K Oyamatsu… - Progress of Theoretical …, 2014 - academic.oup.com
Neutron stars, produced at the death of massive stars, are often regarded as giant neutron-
rich nuclei. This picture is especially relevant for low-mass (below about solar mass,) …
