Description

I will give an introduction to Fermion-Boson-Stars, Neutron Stars with an additional massive, self-interacting complex scalar field, which interact only gravitationally. I explore its history, the mass-radius-relations, tidal deformability, and compare to observations from HESS, NICER, and LIGO.
