Heavy baryons in compact stars

A Sedrakian, JJ Li, F Weber - Progress in Particle and Nuclear Physics, 2023 - Elsevier
We review the physics of hyperons and Δ-resonances in dense matter in compact stars. The
covariant density functional approach to the equation of state and composition of dense …

Do hyperons exist in the interior of neutron stars?

D Chatterjee, I Vidana - The European Physical Journal A, 2016 - Springer
In this work we review the role of hyperons on the properties of neutron and proto-neutron
stars. In particular, we revise the so-called “hyperon puzzle”, go over some of the solutions …

GW170817: Constraining the nuclear matter equation of state from the neutron star tidal deformability

T Malik, N Alam, M Fortin, C Providência, BK Agrawal… - Physical Review C, 2018 - APS
Constraints set on key parameters of the nuclear matter equation of state (EoS) by the
values of the tidal deformability, inferred from GW170817, are examined by using a diverse …

Relativistic mean-field hadronic models under nuclear matter constraints

M Dutra, O Lourenço, SS Avancini, BV Carlson… - Physical Review C, 2014 - APS
Background: The microscopic composition and properties of infinite hadronic matter at a
wide range of densities and temperatures have been subjects of intense investigation for …

Early appearance of isobars in neutron stars

A Drago, A Lavagno, G Pagliara, D Pigato - Physical Review C, 2014 - APS
We discuss the formation of Δ isobars in neutron star matter. We show that their threshold
density strictly correlates with the density derivative of the symmetry energy of nuclear …

New hyperon equations of state for supernovae and neutron stars in density-dependent hadron field theory

S Banik, M Hempel… - The Astrophysical Journal …, 2014 - iopscience.iop.org
We develop new hyperon equation of state (EoS) tables for core-collapse supernova
simulations and neutron stars. These EoS tables are based on a density-dependent …

Hyperons in neutron star matter within relativistic mean-field models

M Oertel, C Providência, F Gulminelli… - Journal of Physics G …, 2015 - iopscience.iop.org
Since the discovery of neutron stars with masses around $2\;{{M} _ {\odot}} $ the
composition of matter in the central part of these massive stars has been intensively …

Hypernuclei and massive neutron stars

M Fortin, SS Avancini, C Providência, I Vidaña - Physical Review C, 2017 - APS
Background: The recent accurate measurement of the mass of two pulsars close to or above
2 M⊙ has raised the question of whether such large pulsar masses allow for the existence …

Bayesian inference of signatures of hyperons inside neutron stars

T Malik, C Providência - Physical Review D, 2022 - APS
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 …

Astrophysics and nuclear physics informed interactions in dense matter: Inclusion of PSR J0437-4715

T Malik, V Dexheimer, C Providência - Physical Review D, 2024 - APS
We investigate how vector-isoscalar and vector-isovector interactions can be determined
within the density regime of neutron stars (NSs), while fulfilling nuclear and astrophysics …
