Stability analysis of apsidal alignment in double-averaged restricted elliptic three-body problem by Neishtadt, Anatoly, Sheng, Kaicheng, Sidorenko, Vladislav

“… We show that they are stable in the linear approximation. The Arnold–Moser stability theorem provides sufficient conditions under which this means stability in a nonlinear sense too. These conditions are violated for parameters of the problem that belong to a set formed by a finite number of analytic curves in the parameters’ plane. As it turned out, in the system under consideration, violation of these conditions in some cases actually leads to an instability…”
