Colapso gravitacional de fluido perfeito em espaços-tempos circularmente simétricos com auto-similaridade cinemática
Perfect fluid with kinematic self-similarity is studied in 2 + 1 dimensional spacetimes with circular symmetry and various exact solutions to the Einstein field equations are given. These include all the solutions of dust and stiff perfect fluid with self-similarity of the first kind (homothetic) …

Colapso gravitacional e estruturação da seção marinha da bacia da Foz do Amazonas no contexto de múltiplos níveis de destacamento
The Amazon deep-sea fan is part of the Foz do Amazonas Basin. It comprises a thick prograding siliciclastic prism (~ 10 km thick) related to the Amazon River input since Upper Miocene (~10 Ma). Gravity-driven deep-water fold-and-thrust belts stand as the most remarkable structures along the margin, …

Hydrodynamical simulations of dust traps in protoplanetary disks
… encontrar que se podrían formar debido al colapso gravitacional, y de un núcleo masivo el cual acreta material. En el escenario de acreción de núcleo el polvo debe crecer varios ordenes de magnitud de manera eficiente. Un lugar en el disco en que el polvo logra concentrarse por un largo …
