Title: A survey of compact objects in scalar tensor theories
Abstract: I will discuss some explicit solutions of higher order scalar tensor theories. We will start by reviewing classical GR solutions and some of their key properties such as integrability of geodesics in Kerr spacetime. We will then construct stealth solutions, ie solutions that are still Einstein metrics but with a non trivial scalar field. We will construct solutions which are distinct from GR, static and [...]
