Introduction to nuclear physics of neutron stars — •Ingo Tews — Theoretical Division (T-2), Los Alamos National Laboratory, Los Alamos, NM 87545

Neutron stars are fascinating stellar objects born in core-collapse supernovae. Their masses reach up to two solar masses but their radii are of the order of only 10 km. Due to these extremely high densities, up to 10¹⁵ g/cm³ in their cores, neutron stars represent ideal laboratories for fundamental physics. In particular, neutron stars probe nuclear physics at densities far beyond the regime accessible in terrestrial experiments.

In this presentation, I will give an introduction to the nuclear physics relevant for the structure of neutron stars. I will present current state-of-the-art results for the equation of state of neutron-star matter and neutron-star properties, and discuss current observational limits.
