Description

Neutron stars are unique laboratories for studying strongly interacting, neutron-rich matter under extreme conditions. While much has already been learned about neutron stars in the era of multi-messenger astronomy, many key questions remain, especially regarding the composition and equation of state (EOS) of the ultra-compressed matter in their inner cores. At the same time, chiral effective field theory (EFT) has developed into a powerful framework to study nuclear matter properties with quantified uncertainties in the moderate-density regime for modeling neutron stars.

In this talk, I will discuss recent developments in EFT-based nuclear matter calculations and their implications for the structure of neutron stars. I will also show how EFT enables statistically robust comparisons among competing nuclear theory predictions, nuclear experiments, and observational constraints on the EOS.
