Neutron stars provide a unique laboratory for probing the properties of dense nuclear matter under extreme conditions of density. Understanding their internal structure requires a description of the Equation of State of matter at very high densities, which remains one of the main challenges in modern nuclear physics and astrophysics.

A Chiral Effective Field Theory approach can quite...

20. Neutron star crust from Bayesian-constrained unified EoS with ab initio input

The nuclear equation of state (EoS) governs the structure of neutron stars and can be constrained by linking information from astrophysical observations, ab initio nuclear theory, and heavy-ion collisions within a Bayesian framework. In this work, we extend a unified meta-modeling approach to the EoS by implementing low-density corrections informed by energy density functionals calibrated to...

38. Nucleon-nucleon correlation functions from different interactions

More and more data on correlation functions between hadrons as they can be measured in heavy-ion collisions using the femtoscopy technique [1,2] have recently become available. This applies not only to the nucleon-nucleon system but also to the hyperon-nucleon system. Thereby, they might help in the future to constrain hyperon-nucleon interactions.

As a first step in this direction, it is...

11. Relativistic corrections and three-nucleon forces in neutron star matter

We discuss the inclusion of relativistic boost corrections in the correlated basis function (CBF) effective nuclear Hamiltonian. In this framework, a well-behaved nuclear effective interaction is derived from a realistic Hamiltonian through the CBF formalism and cluster expansion techniques. This approach has proven to be remarkably powerful in computing both equilibrium and transport...
