The presence of rare elements in the atmosphere of a distant planet: Kelt-9b, four thousand degrees Celsius, exhibits elements in the Swan constellation that have never been previously revealed in the atmosphere of an out-of-plan or non-solar planet. The research team led by Jens Hoeijmakers and Kevin Heng presented their results in Astronomy & Astrophysics.
Last year, the presence of iron and titanium atoms on the planet was discovered, researchers from the University of Bern and Geneva now found sodium, magnesium, chromium and rare earth, scandium and yttrium. The last three have never been shown in an exobjective atmosphere before.
They rarely occur on Earth and are used primarily in modern materials and tools. Scandium is used, for example, in high-performance stadiums, magnetic data carriers and laser crystals. Yttrium is used in special alloys, fluorescent lamps and nuclear medicine.
Kelt-9b, 650 miles from Earth, is very close to its star. Because of the heat that rages on the planet called “hot Jupiter”, every element almost evaporates from the surface and gets into the atmosphere. The researchers examined this composition with a very sensitive spectrograph of a huge telescope.
Atoms of different elements absorb a special part of light. Each element leaves a special fingerprint of the wavelengths absorbed by it, which can be observed with the aid of a spectrograph. Based on the pattern of absorbing lines, researchers can guide the composition of the distant planets’ atmosphere.
“Based on our analysis, we can also estimate the height at which the atoms are absorbed by the atoms in the atmosphere of the planet,” said researcher Jens Hoeijmakers, adding that they want to learn more about the atmosphere of this exoplanet and other planets that similarly high temperatures as Kelt-9b.
There is a good chance that we can find life-like signs on an exoblan with the same technique, ”Heng said. The researcher explained that their research is intended to lay the foundations for the development and development of the solar system and the origin of life.
