Formed in the aftermath of gravitational core-collapse supernova explosions, neutron stars are unique cosmic laboratories for probing the properties of matter under extreme conditions that cannot be reproduced in terrestrial laboratories. The interior of a neutron star, endowed with the highest magnetic fields known and with densities spanning about ten orders of magnitude from the surface to the centre, is predicted to exhibit various phases of dense strongly interacting matter. During this talk, the series of models of dense matter developed by the Brussels-Montreal collaboration to describe all stellar regions in a unified and consistent way will be reviewed. The ongoing developments will be also presented. The predictions from these models will be discussed and compared to astrophysical observations, including the gravitational-wave signal GW170817 from a binary neutron-star merger as well as recent data from NICER.
