摘要:

The Stark problem is a gravitational one­body problem with an external force field. It is also known as the accelerated Kepler problem. The system is integrable and seperable under parabolic coordinates. We prove the existence of varies symmetric periodic orbits in Stark problem. We also give some characterization for these orbits. This is a jiont work Ku-Jung Hsu.
