In this contribution, we describe new chemically-equilibrated charge-neutral hybrid equations of state for neutron stars. They present a first-order phase transition to quark matter and differentiate by the particle population considered and how these particles interact. While some equations of state contain just nucleons and up, down-quarks, others also contain hyperons, Delta baryons, and strange quarks. The hybrid equations of state, together with corresponding hadronic ones, are available on the CompOSE repository and can be used for different astrophysical applications.

    A Bayesian analysis of smooth hadron-quark crossover neutron stars using NICER and GW170817 data favors a broad, high-density mixed transition, disfavors pure quark cores, and makes a neutron-star interpretation of GW...
