1. Simulação Gráfica de Buracos Negros utilizando Sistemas de Partículas
The application of Computer Graphics tools in the nature phenomena simulation have been presenting a series of proposals since its creation. Over the years this task has gained a characteristic trait that makes it closer to the reality, both visually as by the abstraction strategies used. However, the specific application of this Computer Science area for th

2. Analytical and numerical approaches to study the gravitational capture in the four-body problem
The objective of this paper is to study the problem of gravitational capture in the bi-circular restricted four-body problem. A gravitational capture occurs when a massless particle changes its two-body energy around one celestial body from positive to negative without the use of non-gravitational forces. It is mainly studied the effect of the fourth-body in

3. Orbital evolution and maneuvers around non-spherical bodies / Evolução orbital e manobras em torno de corpos não-esféricos
In the last years several asteroids had their shapes identified using images from space probes or through the indirect radar data determination. In a general way, these asteroids have forms quite different from spherical. Conventional spherical harmonic representations of the gravitational potential of such bodies require expansions of high degree and order,

4. Manobras orbitais aplicadas aos problemas de dois e tres corpos
In the space activities, it is of great importance the study of the trajectories that the space vehicles should follow to complete a mission. With that motivation, the present research is concentrated in the study of those trajectories, under the dynamics given by: a)The traditional Problem of Two Bodies with Keplerian orbits where the space vehicle is suppo
