Perturbative analysis in planetary gravitational lensing
Received 26 January 1999 / Accepted 30 April 1999
The traditional perturbative method is applied to the case of gravitational lensing of planetary systems. A complete and detailed description of the structure of caustics for a system with an arbitrary number of planets can be obtained. I have also found precise analytical expressions for microlensing light curves perturbed by the presence of planets.
