11:00 am Diogo Merguizo Sanchez Instituto Nacional de Pesquisas Espaciais - INPE On the applications of perturbation maps
Abstract: Perturbation maps are grids of initial conditions built with the method of the integral of the disturbing accelerations, or simply PI Method. Each point in the map shows the value of the PI Method for a given initial condition. There are four types of maps which reveal different aspects of the perturbations that act over a particle around a central body. For example, the perturbation maps can be used to measure the relevance of a perturbation effect on a system. They also can be used to assess the stability of a particle in a system as well as how much the particle deviates from a reference orbit. Therefore, perturbation maps can be used to study the dynamics of natural and artificial bodies. This presentation will focus on the application of the perturbation maps on some systems, such as the dynamics of the Haumea's ring, artificial satellites around the Earth, and a spacecraft in the 2001 SN263 system.
