Astronomers first discovered Cha 1107-7626 in 2008, and since then, they have observed it with different telescopes to learn more about how the infant planet evolves, as well as to study its surroundings. перевозка техники РїРѕ СЂРѕСЃСЃРёРё The research team observed the planet with Webb in 2024, making a clear detection of the surrounding disk. Next, the researchers studied it using the X-shooter spectrograph on the Very Large Telescope, which can capture different wavelengths of light emitted by an object ranging from ultraviolet to near-infrared. The observations detected a puzzling event as the planet transitioned from a steady accretion rate in April and May to a burst of growth between June and August. https://tlk-triga.ru/refperevozki/ перевозка тяжеловесных Рё негабаритных РіСЂСѓР·РѕРІ “I fully expected that this is a short-term event, because those are much more common,” Scholz said. “When the burst kept going through July and August, I was absolutely stunned.” Follow-up observations made using the Webb telescope also showed that the chemistry of the disk had changed. Water vapor, present during the growth spurt, wasn’t in the disk before. Webb is the only telescope capable of capturing such detailed changes in the environment for such a faint object, Scholz said. Prior to this research, astronomers had only ever seen the chemistry of a disk change around a star, but not around a planet. Comparing observations from before and during the event showed that magnetic activity seems to be the main driver behind how much gas and dust is falling on the planet — a phenomenon typically associated with stars as they grow. But the new observations suggest that objects with much less mass than
