fast Summary
- Sub-Neptunes are a common type of exoplanet, larger than Earth but smaller than gas giants, characterized by hazy atmospheres and difficult observation.
- NASA’s James Webb Space Telescope observed TOI-421 b,an exoplanet wiht a clearer atmosphere due to its high temperature (~1,340°F),deviating from previously studied cooler sub-Neptunes.
- Key findings include the presence of water vapor and potential signatures of carbon monoxide and sulfur dioxide in TOI-421 b’s hydrogen-dominated atmosphere. Methane and carbon dioxide were notably absent.
- Researchers hypothesize that TOI-421 b’s hydrogen-heavy atmosphere may reflect the composition of its host star-a Sun-like star unlike other sub-Neptunes that orbit red dwarfs.
- These findings suggest significant diversity in sub-Neptune formation and evolution, prompting further studies to explore broader trends among hot sub-Neptunes.
