[en] The aim of the workshop is to assemble experts from both astrophysics and nuclear physics to discuss the physics of neutron star mergers. In particular, recent developments in the following fields are discussed: Observations of gravitational waves and electromagnetic signals; Simulations of compact object mergers and their neutrino-driven winds; Chemical evolution and nucleosynthesis; Nuclear physics of the r-process: masses, lifetimes, fission; Neutron stars from crust to core and equation of state; Neutrino-matter interactions and oscillation phenomena (nowak)
