Setting the Stage: Planet formation and Volatile Delivery

TL;DR

This review summarizes key concepts and processes in planet formation, emphasizing how volatile compounds are delivered to inner planets, which influences the diversity in planetary atmospheres.

Contribution

It provides a concise overview of the mechanisms involved in planet formation and volatile delivery, integrating recent insights into the field.

Findings

Volatile delivery significantly impacts planetary atmosphere composition.

Different physical and chemical processes shape planetary building blocks.

Protoplanetary disc composition influences planetary diversity.

Abstract

The diversity in mass and composition of planetary atmospheres stems from the different building blocks present in protoplanetary discs and from the different physical and chemical processes that these experience during the planetary assembly and evolution. This review aims to summarise, in a nutshell, the key concepts and processes operating during planet formation, with a focus on the delivery of volatiles to the inner regions of the planetary system.
