"Forbidden" Planet Too Big For Its Star Has An Atmosphere Like None We've Seen Before

Exoplanet TOI-5205 b is weird for a bunch of different reasons, and now we can add its low metallicity to that list.

Giant planet that shouldn’t exist is forcing astronomers to rethink planetary science

An exoplanet, TOI-5205 b, which is almost as large as Jupiter, orbits a small red star. By many estimates, this red star should not have been able to form it due to the star’s mass. The fact that TOI-5205 b exists as it does at all raises intriguing questions about how it came to be. In addition, the James Webb Space Telescope has confirmed that this planet may be even stranger than previously thought. Specifically, the atmosphere of TOI-5205 b …

Giant Planet TOI-5205 b Orbits A Small Red Star - Astrobiology

Massive exoplanet reveals new insights into the formation of planets and their relationship to a host star. Scientists have discovered that a highly unusual giant planet – sometimes called ‘forbidden’ – could have an atmosphere with fewer heavier elements that its host star. University of Birmingham astrophysicist Dr Anjali Piette worked in an international research […] The post Giant Planet TOI-5205 b Orbits A Small Red Star appeared first on A…

Unusually large ‘forbidden planet’ is chemically dissimilar to host star

New Delhi: The James Webb Space Telescope has peered into the atmosphere of the exoplanet designated as TOI-5205 b, and discovered that the atmosphere has fewer heavier elements than its host star. The observations improve the scientific understanding of the formation of gas giants, and the processes at work in the infancy of a star. TOI-5205 b is a gas giant, about the size and mass of Jupiter orbiting a host star that contains only four times …
