Periodic solutions and regularization of a Kepler problem with time-dependent perturbation
Alberto Boscaggin, Rafael Ortega, Lei Zhao
We consider a Kepler problem in dimension two or three, with a time-dependent -periodic perturbation. We prove that for any prescribed positive integer , there exist at least…

Periodic solutions of a perturbed Kepler problem in the plane: from existence to stability
Alberto Boscaggin, Rafael Ortega
The existence of elliptic periodic solutions of a perturbed Kepler problem is proved. The equations are in the plane and the perturbation depends periodically on time. The proof is…
