Highly dense and isospin asymetric matter is partly out of the reach of nuclear laboratories on Earth but comprises the deepest shells of the highly compact astrophysical objects that are Neutron Stars. An entire field of nuclear astrophysics, which includes multi-messenger astronomy, is devoted to exploring dense matter by observing neutron stars from their birth in core collapse supernovae...
Neutron stars are the sites of the densest, most extreme matter in the Universe, and are natural laboratories in which to explore dense matter physics. I will discuss constraints on the equation of state and the nuclear symmetry energy available through current and future multimessenger observations of neutron star mergers, and how these can complement terrestrial collider experiments.
The question of the nuclear symmetry energy is of great importance in physics, with numerous implications for a variety of fields. There exist different approches to solve this question, either experimentally, theoretically, or with astrophysical observations. For the latter, neutron stars are unique laboratories to probe nuclear-rich matter beyond saturation density, and therefore to help...
