We present a novel relativistic density-functional approach to modeling quark matter with a
mechanism to mimic confinement. The quasiparticle treatment of quarks provides their …

This self-contained introduction to compact star physics explains important concepts from
areas such as general relativity, thermodynamics, statistical mechanics, and nuclear …

Compact stars may contain quark matter in their interiors at densities exceeding several
times the nuclear saturation density. We explore models of such compact stars where there …

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 …

We explore systematically a new class of two-phase equations of state (EoS) for hybrid stars
that is characterized by three main features: 1) stiffening of the nuclear EoS at …

In agreement with the constantly increasing gravitational wave events, new aspects of the
internal structure of compact stars can be considered. A scenario in which a first-order …

A two-phase description of the quark–nuclear matter hybrid equation of state that takes into
account the effect of excluded volume in both the hadronic and the quark-matter phases is …

The first direct detection of gravitational waves has opened a new window to study the
Universe and would probably start a new era: the gravitational wave Astronomy …

We generalize a recently proposed confining relativistic density-functional approach to the
case of density-dependent vector and diquark couplings. The particular behavior of these …

We investigate the robustness of third family solutions for hybrid compact stars with a quark
matter core that correspond to the occurrence of high-mass twin stars against a softening of …
