The neutron-matter equation of state connects several astrophysical systems over a wide density range. Among these are neutron-rich nuclei, which are relevant for the r-process, and neutron stars, which contain the densest form of matter we know to exist in the cosmos. An accurate description of the neutron-matter equation of state is crucial to describe these systems and requires precise many-body methods in combination with a systematic theory for nuclear forces. Chiral effective field theory (EFT) is such a theory. It provides a systematic framework for the description of low-energy hadronic interactions and enables calculations with controlled theoretical uncertainties. In this talk, I present recent constraints on the neutron-matter equation of state from chiral EFT in combination with advanced many-body methods. Furthermore, I will discuss the impact of these results for astrophysics: for the supernova equation of state, the symmetry energy and its density derivative, and for the structure of neutron stars.
