Micaela Oertel (Observatoire Astronomique de Strasbourg, France) Opis: The first detection of gravitational waves from a merging neutron star binary system and the accompanying observations of electromagnetic counterparts in 2017 demonstrated the enormous potential of multi-messenger astronomy for understanding the properties of ultra-dense (and hot) matter. Neutron stars — relics of the gravitational collapse and subsequent supernova explosions of massive stars at the end of their life- comprise the highest densities of matter that can stably exist in the Universe. During this talk, I will discuss some details about the complex microphysics involved and the possibilities for insights into matter under these extreme conditions from future detections of neutron star-related astrophysical events. Among others, results will be shown illustrating the capacity of multi messenger observations to give us hints about a possible phase transition in neutron star matter.
