Outline of Final Research Achievements |
We have investigated the dependence of the temporary capture of asteroids by a planet (ie, Jupiter, Saturn, or Mars) on their original heliocentric semimajor axes through analytical arguments and numerical orbital integrations in order to discuss the origins of irregular satellites of giant planets. An analytical investigation reveals the intrinsic dynamics of these dependences and gives boundary semimajor axes for capture. The numerical calculations support the idea of deriving analytical formulae and confirm their dependence.
