Despite their long history and astrophysical importance, some of the key properties of
neutron stars are still uncertain. The extreme conditions encountered in their interiors …

X-ray pulse profile modeling of PSR J 0740+ 6620, the most massive known pulsar, with
data from the NICER and XMM-Newton observatories recently led to a measurement of its …

Observations of neutron stars, whether in binaries or in isolation, provide information about
the internal structure of the most extreme material objects in the Universe. In this work, we …

The general behavior of the nuclear equation of state (EOS), relevant for the description of
neutron stars (NSs), is studied within a Bayesian approach applied to a set of models based …

The impact of anisotropic pressure models in neutron stars (NSs) is increasing their
compactness. Therefore, for the relatively soft NS equation of state (EOS), we can still obtain …

The possible signatures of the presence of hyperons inside neutron stars are discussed
within a Bayesian inference framework applied to a set of models based on a density …

We point out that there is an upper bound on the speed of sound squared given by cs 2≤
0.781 valid for all known systems described by relativistic transient hydrodynamics where …

We construct new effective interactions using the relativistic mean-field models with the
isoscalar-and isovector-meson mixing, σ 2 δ 2 and ω μ ω μ ρ ν ρ ν. Taking into account the …

We investigate the possibility that GW170817 was not the merger of two conventional
neutron stars (NS), but involved at least one if not two hybrid stars with a quark matter core …

The impacts of various symmetry energy parameters on the properties of neutron stars (NSs)
have been recently investigated, and the outcomes are at variance, as summarized in Table …
