TITLE: Dynamical Evolution of eccentric binary systems

ABSTRACT: The orbital evolution of a binary system is driven by many and different dynamical processes that occur between the components of the binary. All of these processes act as perturbations to the classic two-body problem and drive the time-evolution of the system. In the first part of the talk I will discuss the general formalism used to describe the effect of these perturbations on the orbital evolution of the binary, focusing on the case of mass-loss/transfer processes in eccentric binary systems. In the second part of the talk, I will show how the same formalism can be used to describe the dynamical evolution of massive black hole binaries due to dynamical friction.
