This "forbidden" exoplanet has an atmosphere scientists can't explain The findings, published in The Astronomical Journal, come from an international team led by Caleb Cañas of NASA's Goddard Space Flight Center, with contributions from Carnegie Science's Shubham Kanodia and others. A Giant Planet Orbiting a Small Star TOI-5205 b is about the size of Jupiter but orbits a much smaller star, one that is roughly four times Jupiter's size and only about 40 percent as massive as the Sun. When the planet passes in front of its star in an event known as a "transit," it blocks about six percent of the star's light. During these transits, astronomers used spectrographs to break the starlight into its component colors. This technique allows them to identify the chemical makeup of the planet's atmosphere and gain insight into how it formed and evolved alongside its host star. A Puzzle for Planet Formation Theories Planets typically form within a rotating disk of gas and dust surrounding a young star. While this process is widely accepted, systems like TOI-5205 b challenge existing models. Massive planets orbiting small, cool stars at close distances are difficult to explain using current theories. To investigate these unusual systems, Kanodia, Cañas, and Jessica Libby-Roberts of the University of Tampa...

Giant 'forbidden planet' orbiting small star shows an unusually low-metal atmosphere Scientists have discovered that a highly unusual giant planet—sometimes called "forbidden"—could have an atmosphere with fewer heavier elements than its host star. University of Birmingham astrophysicist Dr. Anjali Piette worked with an international research team to analyze James Webb Space Telescope data from the exoplanet TOI-5205 b. This is a Jupiter-sized planet orbiting a star about four times the size of Jupiter and about 40% the mass of the sun.

Gemini South confirms long-suspected link between the composition of exoplanets and their host stars Astronomers have discovered that a giant planet, WASP-189b, echoes the composition of its host star, providing the first direct evidence of a foundational concept in astrobiology. This discovery was achieved through the first-ever simultaneous measurement of gaseous magnesium and silicon in a planet's atmosphere. The team used the Gemini South telescope, one half of the International Gemini Observatory. The findings are published in the journal Nature Communications.
