Exoplanet Statistics and Theoretical Implications

TL;DR

This paper reviews recent statistical findings on exoplanet populations, especially within 1 AU, and discusses their implications for theories of planet formation and system evolution.

Contribution

It provides a comprehensive review of recent exoplanet statistical data and explores their impact on theoretical models of planetary system development.

Findings

Kepler mission has thoroughly surveyed the inner planetary regions.

Exoplanet distributions suggest specific formation and evolution pathways.

Statistical results inform and constrain planet formation theories.

Abstract

In the last few years, significant advances have been made in understanding the distributions of exoplanet populations and the architecture of planetary systems. We review the recent progress of planet statistics, with a focus on the inner <~ 1 AU region of the planetary system that has been fairly thoroughly surveyed by the Kepler mission. We also discuss the theoretical implications of these statistical results for planet formation and dynamical evolution.
