Secular models and Kozai resonance for planets in coorbital non-coplanar motion

In this work, we construct and test an analytical model and a semi-analytical secular model for two planets locked in a coorbital non-coplanar motion, comparing the results with the restricted three-body problem. The analytical average model replicates the numerical N-body integrations, even for moderate eccentricities (≲0.3) and inclinations (≲10°), except for the regions corresponding to quasi-s...
