The recent direct observation of gravitational wave event GW170817 and its GRB170817A
signal has opened up a new window to study neutron stars and heralds a new era of …

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 …

Following the idea that a stable sexaquark state with quark content (uuddss) would have
gone unnoticed by experiments so far and that such a particle would be a good dark matter …

The existence of quark matter inside the heaviest neutron stars has been the topic of
numerous recent studies, many of them suggesting that a phase transition to strongly …

We introduce a family of equations of state (EoS) for hybrid neutron star (NS) matter that is
obtained by a two-zone parabolic interpolation between a soft hadronic EoS at low densities …

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 …

The effect of pasta phases on the quark-hadron phase transition is investigated for a set of
relativistic mean-field equations of state for both hadron and quark matter. The results of the …

We follow the idea that the QCD phase diagram may be described by a crossover from a
hadron resonance gas to perturbative QCD using the switch function ansatz of Albright …

We present a systematic investigation of the possible locations for the special point (SP), a
unique feature of hybrid neutron stars in the mass‐radius diagram. The study is performed …

We construct equilibrium models of uniformly and differentially rotating hybrid hadron-quark
stars using equations of state (EOSs) with a first-order phase transition that gives rise to a …
