An illustration shows three exoplanets a differing distances around a star experiencing different lavesl of radiation and gravitational forces that are stripping their atmospheres at different rates.A scientist has learned more about the violent processes that rip atmospheres away from planets, finding that squashing and squeezing by a parent star can contribute to this process.
Previously, modeling has been employed to understand the physical mechanisms driving hydrodynamic escape, but these models have been complex and often resulted in obscure conclusions. For planets that can't experience hydrodynamic escape due to high internal energy, Jianheng found that a modified Jeans parameter accounting forJames Webb Space Telescope could help hunt for habitable alien worlds
The findings could help scientists better determine how low-mass planets' atmospheres change over time, helping to paint a better picture of theto keep talking space on the latest missions, night sky and more! And if you have a news tip, correction or comment, let us know at:
