Analytical continuation of stability of periodic orbits in the restricted three-body problem

A supplement to the theory of analytical continuation of circular orbits in the restricted three-body problem is presented. The first order stability is given analytically to the first power of mass parameter . The theory of the Kirkwood gaps is discussed from this point of view. The stability limit which should determine the size of accretion discs in binaries is found to be in good agreement with earlier numerical experiments for < 1/2.
