This programme is designed to bring together researchers on neutron star dynamics, condensed matter and nuclear physics as well as experts on the surface layers and the magnetosphere. The aim is to discuss synergies that can arise from collaboration and exchange of expertise. Key questions are: What input from microphysics calculations do we need to build realistic theoretical models? What bounds can the dynamical models in conjunction with observations provide on the state of matter at extreme densities? How do we use observations to constrain these parameters? If a neutron star is oscillating, how does information of the oscillations propagate to the observers?
