Researchers analyzing data from NASA’s James Webb Space Telescope report new findings about the exoplanet HD 80606 b, a gas giant orbiting a Sun-like star. The planet has a mass estimated at about four times that of Jupiter and follows a highly elliptical orbit, bringing it unusually close to its host star at certain points in its year. This close approach results in strong heating of the planet’s atmosphere, which the team describes as the planet being “roasted.” The researchers are presenting their study and preliminary results at the 248th meeting of the American Astronomical Society (AAS248) in Pasadena, California. NASA’s account highlights Webb’s role in capturing observations of the planet during the period of intense stellar irradiation associated with its near-star passages. Phys.org similarly summarizes the same Webb-based analysis and the planned presentation timing at AAS248. Across the reports, the key points are the use of Webb observations, the planet’s approximate mass, its extremely elliptical orbit, and the resulting extreme heating near periastron.
