[Okc-wp4] Next EO meeting on Thursday 19th of April (in A4:1003 at 13:15)

[Francesco Taddia]

Hi all,

We have a change in the room for our next EO meeting on thursday:
we will be in A4:1003 (the room right below the normal meeting room, on the 4th floor).

cheers

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.
