Understanding the interior composition of neutron stars is an important goal of astrophysics and fundamental physics. By mid-2019, the promising results of the Neutron Star Interior Composition ExploreR mission (NICER) on the dense matter equation of state will be available. Around that time, run O3 of the LIGO/Virgo collaboration will be in progress (or completed) with several expected new NS-NS mergers discoveries.

This Special Session aims at discussing recent results of the various observational methods giving access to the dense matter properties: gravitational waves from neutron star mergers (LIGO/Virgo), the NICER mission, thermal emission from the surface of neutron stars, and other existing methods. The theoretical modelling of the dense matter equation of state can also be discussed in light of these new results.

Finally, some time will be dedicated for the future of the field, in particular how future missions/experiments will provide the next generations constraints for the better understanding of the dense matter equation of state.
