In orbital dynamics, minor bodies are those that have size (and mass) much smaller than at least one of the other bodies (called primaries) of the system that belong to. One case very common in astronautics is the case of a spacecraft traveling within the sun-earth-moon system. This kind of characteristic makes the dynamics of the system to present some peculiarities. One of them is the f…
One of the most important subjects of debate in the formation of the solar system is the origin of Earth's water. Comets have long been considered as the most likely source of the delivery of water to Earth. However, elemental and isotopic arguments suggest a very small contribution from these objects. Other sourceshave also been proposed, among which, local adsorption of water vapor onto…

Irregular bodies are objects present throughout the Solar System. Their sizes and shapes make them have different dynamic and physical characteristics, making their study more complex than other objects. There are numerous amounts of bodies that belong to this category, including small satellites, comets and asteroids. Scientific interests in these bodies permeate fields that include fact…
The formation of Uranus and Neptune is one of the great challenges of the planetary formation models. Most models assume that supermassive planetary embryos exist beyond Saturn's orbit, and by colliding with each other and/or accreting particles with sizes of cm and mm (known as pebbles) give rise to the Uranus and Neptune cores shortly before the solar nebula dissipation. The models fail…
In general, small bodies of the solar system, as asteroids, comets and many planetary satellites have highly irregular shapes. The gravitational potential around these bodies show significant complexity. Since many space missions are being developed to explore such kind of bodies, it is extremely important to understand the dynamics around them. In this project will be studied orbits arou…
For simplicity, most planet formation models assume that collisions during the intermediate and final phases of planetary formation are constructive. This type of approach has been used both in solar system and exoplanet formation models. The objective of this master's thesis project is to study the impact of a more realistic collision treatment in numerical simulations modeling the forma…
The current plan of activities involve the stability around the triple system 2001SN263, as well as the formation of bodies similar to Alpha. With relation to the stability, the novelties are the inclusion of the perturbations due to the solar radiation pressure and the gravitational potential assuming the irregular shape of the bodies. With respect to the shape of Alpha, the larger body …

The magma oceans on the surface of planets are an important issue in understanding the evolution of atmospheric composition and the mantle-to-core mass ratio of planets. The molten magma is constantly vaporized releasing heavy chemical species from the mantle into the atmosphere. The atmospheric escape of these heavy materials from the magma is favored when in contact with a hydrogen atmo…
The project consists of analyzing Cassini occultation data of the Saturn's D ring. This ring is the innermost ring of Saturn, which is very affected by the planet's gravitational field. Due to its closeness, it is very difficult to observe and few works have been made to study this ring.Cassini occultations revealed several narrow ringlets in the D ring, smaller than 1 km wide. These ring…
If it were to become evident that dangerous changes in global climate were inevitable, despite reducing greenhouse gas emissions, active strategies to avoid climate change in the Earth on an emergency basis might be useful. Several space-based methods to date regarding the reduction of solar insolation, including shading the Earth with a particle ring, or shading the Earth with solid refl…
