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
the structure and evolution of compact stars. A unified EoS should describe the crust and the …

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 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 …
