Activity

The aim is to analyze the co-orbital motion by means of perturbation methods applied to the third-body effect in the orbital elements evolution and, at the same time, by means of the restricted three-body problem and the corresponding invariant objects. 

The focus is to understand the relationship between the two approaches and the possible transition towards different orbital regimes. 
A special emphasis is given to apply the analysis and the results to asteroidal motion.
