Title: Towards the binary compact object formation as an effective field theory.
Abstract: To solve the dynamics of a pair of heavy and compact objects through the exchange of gravitational degrees of freedom and emitting gravitational waves we can set the problem in an effective field theory framework, in the non relativistic general relativity formulation known as effective field theory for extended objects. The two-body problem exhibits a clear separation of scales: The size of the compact objects, the orbital separation and the gravitational wavelength, all controlled by the same expansion parameter. This approach is a way of organizing systemastic expansions in powers of ratios of scales. We describe how to "integrate out" physics at each of the scales to obtain a theory with well defined rules for calculating observables. A possible extension of this idea to formulate the compact object formation in this framework is discussed.
