No Giant Planet Pileup Near 1 AU
Alexander W. Wise, Sarah E. Dodson-Robinson

TL;DR
This study challenges the previously suggested pileup of giant exoplanets near 1 AU by applying a Bayesian analysis to linear-spaced data, revealing the pileup is not statistically significant.
Contribution
It introduces a Bayesian Blocks approach to analyze semimajor axis distributions, questioning prior visual claims of a planet pileup near 1 AU.
Findings
The apparent pileup near 1 AU is not statistically significant.
Log-spaced distributions can be misleading for feature detection.
Bayesian Blocks analysis provides a more robust method for distribution analysis.
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.
