- Formation and evolution of ring structures around small bodies in the Solar System: application to Centaurs., BP.DR
Abstract
Recent advances in observational astronomy have enabled a detailed study ofsmall bodies in the Solar System, including Centaurs, Trans-Neptunian Objects (TNOs),and dwarf planets. Stellar occultations have revealed ring systems around bodiessuch as Chariklo, Haumea, and Quaoar, challenging our understanding of these distantobjects. While planetary rings have been extensively studied, the…
- Numerical simulations of planetary rings using SPH, BP.IC
Abstract
It was believed that only the giant planets of the Solar System would be able to keep stable ring-shaped structures around them. However, a stellar occultation in 2013 revealed that Chariklo - a Centaur with a radius of 125 km - hosts a ring system composed by two narrow rings with well defined edges. This discovery raised numerous questions related to the origin and stability of this sys…
- Determination of asteroid shapes from lightcurves, BP.IC
Abstract
Asteroids are leftovers from which the planets of our Solar System formed, and they keep valuable information of this formation process. An excellent tool to study these objects are their light curves, which are obtained by monitoring the variation of the object brightness as a function of time. Applying an inversion method upon the light curves it is possible to calculate the spin rate o…
- Longitudinal mapping of the Saturn's F-ring, BP.IC
Abstract
Since it was discovered, the F-ring of Saturn has been extensively studied due to its peculiar structures, such as braids, gaps, and strands. These features made the ring one of the main targets for the Cassini spacecraft cameras. The goal of this work is to create a longitudinal map of the F-ring based on a sequence of images taken by the spacecraft. The images will be navigated in order…
