![Planet growth and migration tracks for the formation of WASP-19 b starting from different initial orbital locations. Solid parts of the tracks indicate the pebble-accretion phase before the planet reached pebble isolation mass, while dotted parts indicate the subsequent gas-accretion phase. Different symbols indicate different disc viscosities (α = 10−3 , 5 × 10−4 , and 10−4 ). The colour of each track represents the resulting atmospheric C/O ratio of the planet. -- [astro-ph.EP]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/07/The-majority.png?resize=1200%2C720&ssl=1)
[astro-ph.EP] Atmospheric compositions of giant exoplanets can retain information about their formation environments, as volatile species condense at different temperatures in protoplanetary discs.

The Origins Of Planets For ArieL (OPAL) Key Science Project: The End-to-end Planet Formation Campaign For The ESA Space Mission Ariel
The growing body of atmospheric observations of exoplanets from space and ground-based facilities showcases how the great diversity of the planetary population is not limited to their physical properties but […]
