Planetary Diversity through Instability and Consolidation of High Multiplicity STIPs
Abstract
In previous work, we conducted a series of simulations to demonstrate the feasibility of in situ formation of giant planets at short orbital periods through the consolidation of planets in high multiplicity STIPs. The resulting planet-planet collisions can generate planetary diversity, depending on the timing of instability in the system. If instability occurs while significant gas is still present, then consolidation can produce critical cores massive enough to initiate runaway gas accretion within the lifetime of the gaseous disk. At the time, however, we did not include gas damping effects. Here, we explore how eccentricity and inclination damping can affect the outcomes of STIP metastability
