Improved characterization of Lagrangian coherent structures through time-scale analysis
Zi'ang Ding, Xavier Tricoche
The computation of Lagrangian coherent structures (LCS) has established itself as a prominent means to reveal significant geometric structures in time-dependent vector fields. Thei…

Extraction and Visualization of Poincaré Map Topology for Spacecraft Trajectory Design
Xavier M. Tricoche, Wayne R. Schlei, Kathleen C. Howell
Mission designers must study many dynamical models to plan a low-cost spacecraft trajectory that satisfies mission constraints. They routinely use Poincaré maps to search for a sui…
