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.

Gemini South Confirms Long-Suspected Link Between the Composition of Exoplanets and Their Host Stars Almost 320 light-years away in the Libra constellation lies WASP-189b, an exoplanet known as an ultra-hot Jupiter (UHJ). UHJs have temperatures high enough to vaporize rock-forming elements like magnesium (Mg), silicon (Si), and iron (Fe), offering a rare opportunity to see these elements using spectroscopy — the technique of breaking up light into its component wavelengths to identify the presence of chemicals. An international team of astronomers led by Jorge Antonio Sanchez, a graduate student at Arizona State University (ASU) observed WASP-189b using the high-resolution Immersion GRating INfrared Spectrograph (IGRINS) when it was mounted on the Gemini South telescope in Chile [1]. This powerful instrument allowed them to simultaneously measure the magnesium and silicon content of the exoplanet’s atmosphere. This is the first time such a measurement has been made, and the data reveal that WASP-189b shares the same magnesium-to-silicon ratio as its host star. This finding provides the first observational evidence of a widely adopted assumption about planet formation, and opens a new route to understand how exoplanets form and evolve. “These discoveries show Gemini's ability to help us understand the characteristics of the remarkable zoo of exoplanets in our solar neighborhood,” says Chris Davis, NSF Program Director for...

Scouring TESS Data With AI Reveals A Hundred New Exoplanets Artificial Intelligence (AI) and Machine Learning (ML) are making a growing contribution to astronomy. As powerful telescopes and large automated surveys become more commonplace, the vast quantities of data they generate demand equally powerful diagnostic tools. The Vera Rubin Observatory and its enormous data-generating capacity drive the point home. The observatory's Legacy Survey of Time and Space generates up to 20 terabytes of data each night, and that data is processed at a dedicated facility. The Rubin Observatory is the current queen of data generation, but exoplanet hunting missions like Kepler and TESS generate their own data that needs analysis. Scientists are still processing it, and as time goes on, they're making more and better use of AI and ML to "mine" that data for unrevealed exoplanets. One group of scientists have developed a ML tool aimed solely at TESS. It's called RAVEN, which stands for RAnking and Validation of ExoplaNets. The scientists who developed it describe RAVEN as "a newly developed vetting and validation pipeline for TESS exoplanet candidates." In newly published research, a team of exoplanet researches used RAVEN to focus on TESS transit data for more than 2 million stars. It's titled "Automatic search for transiting planets...
