We discuss the “constant speed of sound”(CSS) parametrization of the equation of state of
high-density matter and its application to the field correlator method (FCM) model of quark …

By inverting the observational data of several neutron star observables in the three-
dimensional parameter space of the constant speed of sound (CSS) model while fixing all …

The possible presence of deconfined matter in the cores of massive neutron stars is the
subject of a large debate. In this context, it is important to set limits on the size and …

In this paper we calculate the speed of sound for three phases that may exist inside a
magnetized hybrid neutron star at different density regions: A hadronic phase at low …

We aim at contributing to the resolution of three of the fundamental puzzles related to the still
unsolved problem of the structure of the dense core of compact stars (CS):(i) the hyperon …

We point out that the very existence of a “horizontal branch” in the mass-radius
characteristics for neutron stars indicates a strong first-order phase transition and thus …

The recent measurements of the masses of the pulsars PSR J1616-2230 and PSR J0348-
0432 provide independent proof for the existence of neutron stars with masses in range of 2 …

Twin stars-two stable neutron stars (NSs) with the same mass but different radii have long
been proposed to appear as a consequence of a possible first-order phase transition in NS …

We present a multi‐polytrope approach to describe high‐mass twins fulfilling chiral effective
field theory estimations of the neutron star equation of state and test it against the …

We suggest a new Bayesian analysis (BA) using disjunct MR constraints for extracting
probability measures for cold, dense matter equations of state (EoS). One of the key issues …
