The orbital structure of the asteroid belt holds a record of the solar system's dynamical history. The current belt only contains ∼10-3 Earth masses yet the asteroids' orbits are dynamically excited, with a large spread ...

A leading model for the origin of super-Earths proposes that planetary embryos migrate inward and pile up on close-in orbits. As large embryos are thought to preferentially form beyond the snowline, this naively predicts ...

Super-Earths - planets with sizes between the Earth and Neptune - are found in tighter orbits than that of the Earth around more than one third of main sequence stars. It has been proposed that super-Earths are scaled-up ...

We develop a simple model of planetary formation, focusing our attention on those planets with masses less than 10M⊕ and studying particularly the primordial spin parameters of planets resulting from the accretion of ...
