This finding shows that strong #ultraviolet radiation in massive star-forming regions can also drastically alter disc chemistry, and thus the building blocks of future #planets.<br/><br/>👉 Paper link: <a href="https://doi.org/10.1051/0004-6361/202555718">https://doi.org/10.1051/0004-6361/202555718</a> 2025-08-29T09:01:22Z https://yabu.me/nevent1qqsxcav5yrkkjdmhdmw0hy2fsfn9sqhngl0x3336889n20unzvfxkqczypk57dkhc7cfmc2f2s8p5lufjfpqp24u99m7pu7lu46hhq7w82dcjdztt9v 1/ 🚀 Rethinking planet #formation:<br/><br/>Using the James #Webb Space Telescope #JWST, a team of researchers led by Stockholm University’s PhD student Jenny Frediani have found a protoplanetary disc with strikingly high levels of CO₂ – and barely any #water. 🔭<br/><br/>#MPIA&#39;s Maria Claudia Ramírez-Tannus leads the research program XUE, from which the study originates.<br/>#exoplanets <br/><br/>🔭 More details here: <a href="https://www.su.se/english/news/unusual-carbon-dioxide-rich-disc-detected-around-young-star-challenges-planet-formation-models-1.841751">https://www.su.se/english/news/unusual-carbon-dioxide-rich-disc-detected-around-young-star-challenges-planet-formation-models-1.841751</a> 2025-08-29T09:01:01Z
