Recent progress in the physics of neutron stars and black holes

Abstract

I will review the rapid recent progress made in modelling neutron stars in binary system and the associated gravitational-wave emission. In particular, I will discuss how our understanding on the maximum mass and radii of neutron stars has improved with the detection of GW170817. In addition, I will illustrate how the properties of magnetised accretion flows onto black holes represent the ideal tool to understand the properties of matter in strong gravitational fields and to explain the phenomenology of accreting supermassive and stellar-mass black holes. More specifically, I will review the modelling these flows not only onto rotating black holes in general relativity, but also on other more exotic compact objects. These comprise black holes in alternative theories of gravity, but also horizonless compact objects with and without a surface.
