Query: Effective action and linear response of compact objects in Newtonian
  gravity   We apply an effective field theory method for the gravitational interaction
of compact stars, developed within the context of general relativity, to
Newtonian gravity. In this effective theory a compact object is represented by
a point particle possessing generic gravitational multipole moments. The time
evolution of the multipoles depends on excitations due to external fields. This
can formally be described by a response function of the multipoles to applied
fields. The poles of this response correspond to the normal oscillation modes
of the star. This gives rise to resonances between modes and tidal forces in
binary systems. The connection to the standard formalism for tidal interactions
and resonances in Newtonian gravity is worked out. Our approach can be applied
to more complicated situations. In particular, a generalization to general
relativity is possible.
