From the microscopic to the macroscopic world: from nucleons to neutron stars

Understand

Recent observations of neutron-star properties, in particular the recent detection of gravitational waves emitted from binary neutron stars, GW 170817, open the way to put strong constraints on nuclear interactions.

• In this paper, we review the state of the art in calculating the equation of state of strongly interacting matter from first principle calculations starting from microscopic interactions among nucleons.
• We then review selected properties of neutron stars that can be directly compared with present and future observations.
