Título: Invariant Manifolds near L1 and L2 in the Planar Elliptic Restricted Three-Body Problem

Expositor: Gladston Duarte
Institución: AGH University of Science and Technology, Polonia.
Fecha: Martes 28 de junio, 2022.
Horario: 17:00 a 18:00 hrs.
Lugar: Por zoom.

Resumen: In this talk we discuss the connections between the stable and unstable manifolds of tori around the points L1 and L2 of the Planar Elliptic Restricted Three-Body Problem (PERTBP). The study of connections between the invariant manifolds of the periodic orbits around these points, in the Planar Circular RTBP, and the creation of bridges
between dierent types of orbits was already done in [1]. In the case of considering an elliptical movement, we investigate how the analysis of the orbit of comet 39P/Oterma can be improved in a more quantitative way.
We compute the dynamical objects that interact with this comet (mixing the tools presented in [2] and the parallel shooting technique), and use some temporal+spatial sections in the phase space to better visualize these objects together with Oterma, when fitting its data into this model.
