The mean-motion resonance is one of the most interesting phenomena in celestial mechanics. Its importance lies on the comprehension of the formation and long-term stability of planetary systems in close orbits.

Abstract: As a new post-doc of the Physics department, I would like to take this opportunity to introduce myself scientifically. I will discuss my work on "applied dynamics", in which I use the AMUSE framework to model dense stellar systems.
Abstract: At the end of the 19th century the existence os a planet beyond Neptune was in debate. In 1930, Pluto was discovered, but too far from the prediction. In 1992 we found out that Pluto is actually a member of a huge belt of icy bodies orbiting beyond Neptune.
Gr@v member António P. Morais gave a talk at Escola Secundária José Régio in Vila do Conde with title "Do Infinitamente Grande ao Infinitamente Pequeno - uma jornada pelas interações fundamentais na natureza". António was an invited speaker to participate in a sequence of seminars entitled "A Biblioteca convida...", and presented to 11th and 12th grade Science and Technology students the four fundamental interactions in nature and how have they shaped our Universe.
Abstract: In this talk I will present equations for the motion of linear viscoelastic bodies interacting under gravity. The equations are fully three dimensional and allow for the integration of the spin, the orbit, and the deformation of each body.
