Symmetry energy, neutron skin, and neutron star radius from chiral effective field theory interactions

Abstract

We discuss neutron matter calculations based on chiral effective field theory interactions and their predictions for the symmetry energy, the neutron skin of 208 Pb, and for the radius of neutron stars.
