Fundamental physics with neutron stars

Abstract

Neutron stars are rich laboratories of multiple branches of modern physics. These include gravitational physics, nuclear and particle physics, (quantum) electrodynamics, and plasma astrophysics. In this chapter, we present the pioneering theoretical studies and the pivotal historical observations on which our understanding of neutron stars is based on. Then, we discuss the usage of neutron stars as probes of fundamental theories of physics.
