Producing a diversity of super Earths from a diversity of disk conditions
Abstract
Observed multi-planet systems that contain planets larger than Earth yet smaller than Neptune exhibit a diversity in the number of planets and spacing between orbits in the system. Here we investigate what planetary system outcomes arise from different disk mass distributions in terms of solids and from the influence of a depleted gaseous disk using computer simulations of planetary embryos growing and merging. We also compare these planetary system outcomes to the multi-transiting exoplanet systems observed by the Kepler mission. We find that a continuum of disk conditions at early conditions can explain the diversity of observed planetary systems at late times without significant migration of the planet's orbit distance from its star over time.
