In this talk I will shortly review several aspects of the physics of neutron stars. After a general introduction I will present a brief historical overview of the idea of neutron stars as well as of the theoretical and observational developments that followed it from the mid 1930s to the present. Then, I will review few aspects of their observation discussing, in particular, the different types of telescopes that are used, the many astrophysical manifestations of these objects, and several observables such as masses, radii or gravitational waves. Finally, I will briefly summarize some of theoretical issues like their composition, structure equations, equation of state, and neutrino emission and cooling.
The talk will be followed by a meetup with PhDs and Postdocs of the Cluster
