Abstract
To study descriptions of gravitational waves originating from binary systems consisting of black holes and/or neutron stars, two different effective theory approaches are reviewed. The first, the effective field theory approach, integrates out the scales significantly smaller than the wavelength of gravitational waves and constructs an effective action that allows for a diagrammatic interpretation. The second, the Effective One Body approach, generalises the test particle limit and uses resummation methods to describe the gravitational waveform until the final stages of the merger, thus including the merger and ringdown. To understand these approaches better, they will be considered from the general notion of effective theories, and several cases of two-body systems will be discussed in other theories than the theory of General Relativity.
