JWST's first spectrum of a TRAPPIST-1 planet U-M astronomer played key role in study of exoplanet that reveals new insights into its atmosphere and star Date: September 27, 2023 Source: University ...
Using the constrained Nelder-Mead simplex method based on the atmospheric O 2 transmission spectrum, they corrected the atmospheric temperature and pressure distribution, and combined the optimal ...
Astronomers have characterized the atmosphere of a young (20 Myr old) transiting exoplanet and found it to be unusually clear and puffy. By analyzing the planet's atmospheric features, they were able ...
The resulting transmission spectrum is, as you would expect from Webb, the most detailed such spectrum ever taken of an exoplanet. Follow Keith Cooper on Twitter @21stCenturySETI.
In the resulting spectrum of the exoplanet's atmosphere, a small hill between 4.1 and 4.6 microns presents the first clear, detailed evidence for carbon dioxide ever detected in a planet outside ...
This graphic shows the transmission spectrum obtained by Webb observations of rocky exoplanet GJ 486 b. The science team’s analysis shows hints of water vapor; however, computer models show that ...
