: These planets are often located near the inner edge of their star's habitable zone. High surface temperatures can lead to significant water vapor in the atmosphere, creating a powerful greenhouse effect.
Researchers use these models to understand the As these planets age, they may lose their water to space due to photolysis (where light breaks down water molecules) and atmospheric escape. A "hot and wet" planet is often on the brink of becoming a "dry" world, similar to what may have happened in Venus's distant past. Related Study Areas old mature hot wet

The most notable paper discussing this concept is by Selsis et al. (published in Astronomy & Astrophysics ), which examines how planets with high water content change over billions of years. Key Concepts from the Research
