The dynamical structure of the Solar System can be explained by a period of orbital instability experienced by the giant planets. While a late instability was originally proposed to explain the Late Heavy Bombardment, recent work favors an early inst

Transneptunian objects (TNOs) are a source of invaluable information to access the history and evolution of the outer solar system. However, observing these faint objects is a difficult task. As a consequence, important properties such as size and al

The observation of large semi-major axis Centaurs: Testing for the signature of a planetary-mass solar companion

Autor: Ramon Brasser, Jean S. Soares, Rodney S. Gomes

Publikováno v: Icarus. 258:37-49

Several objects whose perihelion lies between Jupiter and Neptune have large semi-major axes a > 100 au, two of them having semi-major axis above 1000 au. Since these objects’ perihelia share the same region as the classical Centaurs, a coherent no

The origin of the orbital structure of the cold component of the Kuiper belt is still a hot subject of investigation. Several features of the solar system suggest that the giant planets underwent a phase of global dynamical instability, but the actua

Is the Grand Tack model compatible with the orbital distribution of main belt asteroids?

Autor: Rodney S. Gomes, Alessandro Morbidelli, Rogerio Deienno, David Nesvorný, Kevin J. Walsh

The Asteroid Belt is characterized by the radial mixing of bodies with different physical properties, a very low mass compared to Minimum Mass Solar Nebula expectations and has an excited orbital distribution. Models of the evolution of the Asteroid
