Abstract.We explore the possible mass radius relation of compact stars for the equation of states with a first order phase transition. The low density matter is described by a nuclear matter equation of state resulting from fits to nuclear properties. A constant speed of sound parametrization is used to describe the high density matter phase with the speed of sound $c_{s}^{2} = 1$cs2=1. A classification scheme of four distinct categories including twin star solutions, i.e. solutions with the… 
Locating the special point of hybrid neutron stars
The special point is a feature unique to models of hybrid neutron stars. It represents a location on their mass–radius sequences that is insensitive to the phase transition density. We consider
Constraining twin stars with GW170817
If a phase transition is allowed to take place in the core of a compact star, a new stable branch of equilibrium configurations can appear, providing solutions with the same mass as the purely
Tidal deformability and other global parameters of compact stars with strong phase transitions
Context. Using parametric equations of state (relativistic polytropes and a simple quark bag model) to model dense-matter phase transitions, we study global, measurable astrophysical parameters of
Third family of compact stars within a nonlocal chiral quark model equation of state
We suggest a class of hybrid compact star equations of state which support the existence of a third family of compact stars composed of a core of two-flavor quark matter and a shell of hadronic
New Constraints on Radii and Tidal Deformabilities of Neutron Stars from GW170817.
A parameterized manner a very large range of physically plausible equations of state (EOSs) for compact stars for matter that is either purely hadronic or that exhibits a phase transition is explored, finding the radius that is statistically most probable for any value of the stellar mass.
Astrophysical Aspects of General Relativistic Mass Twin Stars
In this chapter we will introduce an effective equation of state (EoS) model based on polytropes that serves to study the so called "mass twins" scenario, where two compact stars have approximately
Hybrid stars in the light of the merging event GW170817
We study quark-hadron hybrid stars with sharp phase transitions assuming that phase conversions at the interface are slow. Hadronic matter is described by a set of equations of state (EoS) based on
Electrically charged supermassive twin stars
By assuming that ultra dense hybrid neutron stars are endowed with a distribution of electric charge, we study the corresponding twin star solutions and their properties resulting from a sharp first
Signals in the tidal deformability for phase transitions in compact stars with constraints from GW170817
We compute the tidal deformabilities for neutron star merger for equations of state with a strong first order phase transition producing a new separate branch in the mass-radius diagram. A case is
Twin stars: probe of phase transition from hadronic to quark matter
In agreement with the gravitational-wave events which are constantly increasing, new aspects of the internal structure of compact stars have come to light. A scenario in which a first order


Generic conditions for stable hybrid stars
We study the mass-radius curve of hybrid stars, assuming a single first-order phase transition between nuclear and quark matter, with a sharp interface between the quark matter core and nuclear
Mixed phase effects on high-mass twin stars
Recently it has been found that a certain class of hybrid star equations of state with a large latent heat (strong first order phase transition obtained by a Maxwell construction) between stiff
Characteristics of hybrid compact stars with a sharp hadron-quark interface
Abstract.We describe two aspects of the physics of hybrid stars that have a sharp interface between a core of quark matter and a mantle of nuclear matter. Firstly, we analyze the mass-radius
Constraining and applying a generic high-density equation of state
We discuss the “constant speed of sound” (CSS) parameterization of the equation of state of high density matter, and its application to the Field Correlator Method (FCM) model of quark matter. We
Stable hybrid stars within a SU(3) Quark-Meson-Model
The inner regions of the most massive compact stellar objects might be occupied by a phase of quarks. Since the observations of the massive pulsars PSR J1614-2230 and of PSR J0348+0432 with about two
A two-solar-mass neutron star measured using Shapiro delay
Radio timing observations of the binary millisecond pulsar J1614-2230 that show a strong Shapiro delay signature are presented and the pulsar mass is calculated to be (1.97 ± 0.04)M⊙, which rules out almost all currently proposed hyperon or boson condensate equations of state.
Phase transitions and the mass-radius curves of relativistic stars
The properties of the mass-radius curves of relativistic stellar models constructed from an equation of state with a first-order phase transition are examined. It is shown that the slope of the
High-mass twin stars with a multipolytrope equation of state
We show that in the 3-polytropes model of Hebeler et al. \cite{Hebeler:2013nza} for the neutron star equation of state at supersaturation densities a third family of compact stars can be obtained
Colloquium: Measuring the neutron star equation of state using x-ray timing
One of the primary science goals of the next generation of hard x-ray timing instruments is to determine the equation of state of matter at supranuclear densities inside neutron stars by measuring
Compact stars in a SU(3) Quark-Meson Model
The recent observations of the massive pulsars PSR J1614-2230 and of PSR J0348+0432 with about two solar masses implies strong constraints on the properties of dense matter in the core of compact
