No Giant Planet Pileup Near 1 AU
arXiv:1802.06044 · doi:10.3847/2515-5172/aaaebd
Abstract
A pileup near 1~AU in the semimajor axis distribution of giant exoplanets has been visually identified using log-spaced distribution plots. Here we propose that looking for features in a log-spaced semimajor axis distribution of giant planets is problematic. We use the Bayesian Blocks algorithm to analyze the linear-spaced semimajor axis distribution, and find that the apparent pileup is not significant.
