Date 7/9/2023 2:19:35 PM (MENAFN- Youm7) A study identified 11 chemical elements in the atmosphere of a very hot exoplanet WASP-76 b, and the results indicate that the total composition of the planet reflects the composition of the initial planetary disk from which it was formed, Higher temperatures cause rock-forming elements to evaporate into the atmosphere, and interestingly, the team also noticed that there were no certain elements that require higher temperatures to evaporate, leading to the hypothesis that WASP-76 b might have swallowed material from a Mercury-like planet. An international team led by Stéphane Pelletier, a student at the Trottier Institute for Exoplanet Research at the University of Montreal, recently announced that they have conducted a detailed study of the super-hot giant exoplanet WASP-76 b. Using the MAROON-X instrument on the Gemini-North telescope, the team has been able to identify and measure the abundances of 11 A chemical element in the planet’s atmosphere. These include rock-forming elements whose abundance is not known to the giant planets in the solar system such as Jupiter or Saturn. The team’s study is published in the journal Nature. Hundreds of light-years away can teach us something that would likely be impossible to know regarding our solar system, such is the case with this study.” WASP-76 b is an exotic world, reaching extreme temperatures because it is so close to its parent star, a massive star 634 km away. Light-years in the constellation of Pisces: regarding 12 times closer than Mercury to the Sun, with a mass similar to that of Jupiter, but regarding six times more massive, it is quite “bloated”. Since its discovery by the Wide Angle Search for Planets Program (WASP) in 2013 Many teams have studied it and identified the various elements in its atmosphere. It is worth noting that in a study also published in Nature in March 2020, the team found an iron footprint and hypothesized that there might be iron rain on the planet. Since it is so close to its star, the degree of The temperature of WASP-76 b is well above 2,000 degrees Celsius. At these temperatures, many elements that would normally be rock here on Earth (such as magnesium and iron) are vaporized and exist in gaseous form in the upper atmosphere. Studying this strange planet allows an unparalleled view. It is preceded by the presence and abundance of rock-forming elements in the giant planets, since in cold giant planets such as Jupiter these elements are lower in the atmosphere and impossible to detect. The abundances of many of the elements that Pelletier and his team measured in the atmosphere of an exoplanet – such as manganese and chromium – are magnesium, vanadium, barium and calcium – closely matching those in the host star as well as our sun. This abundance is not random: it is a direct product of the Big Bang, followed by billions of years of stellar nuclear makeup, so scientists measure roughly the same composition in all stars, however, it varies. The results of this new study indicate that giant planets can maintain an overall composition that reflects the composition of the protoplanetary disk from which they formed.MENAFN09072023000132011024ID1106574245 Financial Services “will provide the information “as is” without any representations or warranties … either express or implied.
