Recent progress in the understanding of the high density phase of neutron stars advances the view that a substantial fraction of the matter consists of hyperons. The possible impacts of a highly attractive interaction between hyperons on the properties of compact stars are investigated. We find that a hadronic equation of state with hyperons allows for a first order phase transition to hyperonic matter. The corresponding hyperon stars can have rather small radii of R approximately equal 8 km. 
Hypernuclear Physics for Neutron Stars
Abstract The role of hypernuclear physics for the physics of neutron stars is delineated. Hypernuclear potentials in dense matter control the hyperon composition of dense neutron star matter. The
Structure of Stars and Nuclei
In these lectures, the properties of dense hadronic and quark matter and its relation to compact stars will be discussed. In a bottom-up approach we start with nuclear and hypernuclear physics at low
On the maximum mass of hyperonic neutron stars
Chiral Lagrangian and quark-meson coupling models of hyperon matter are used to estimate the maximum mass of neutron stars. Our relativistic calculations include, for the first time, both Hartree and
The hyperon neutron star mean-field model
The properties of strange neutron stars have been studied with the use of the parameter sets stemming from the effective field theory. The impact of the strength of hyperon interactions on neutron
New possible quark-hadron mixed phase in protoneutron stars.
TLDR
It is shown that a new mixed phase with non-constant pressure could appear in protoneutron stars and it would gradually disappear during deleptonization.
Effects of Δ-Isobars on Neutron Stars
We have investigated the possibility of the presence of the deltas in neutron star matter and their effects on neutron stars. Δ-meson couplings of the theoretical predictions are only restricted in a
The influence of the strength of hyperon-hyperon interactions on neutron star properties
An equation of state of neutron star matter with strange baryons has been obtained. The effects of the strength of hyperon–hyperon interactions on the equations of state constructed for the chosen
Catastrophic rearrangement of a compact star due to the quark core formation
We study properties of compact stars with the deconfinement phase transition in their interiors. The equation of state of cold baryon-rich matter is constructed by combining a relativistic mean-field
Impact of phase transition from neutrons to hyperons in neutron star properties
We revisit the impact of phase transition from neutrons to hyperons in the properties of neutron star using BSP parameter set of relativistic mean field (RMF) model. Similar to the work reported in
The role of nonlinear vector meson interactions in hyperon stars
An extended nonlinear model has been applied to construct a neutron star matter equation of state. In the case of neutron star matter with non-zero strangeness the extension of the vector meson
