Scientists have recently heard of Discovery of barium in two exoplanets have given, while in the atmosphere of exoplanets there are usually elements such as oxygen, carbon and hydrogen.

Astronomers using the VLT telescope at the European Southern Observatory (ESO) have recently announced the discovery of barium in two exoplanets. According to this news, there are two exoplanets that, in addition to strange features such as metal clouds from which liquid metals rain, have one of the heaviest elements in their atmosphere, barium (Ba).

Discovery of barium in two exoplanets

According to a new scientific study published by this group in the journal Astronomy & Astrophysics, barium is the heaviest element found in the atmosphere of an exoplanet. Even in the Earth’s atmosphere, barium atoms are known to be extremely heavy and are commonly combined with other elements to make materials such as oil well drilling fluids, glass-making tools, and paints.

In fact, the name Barim, from The Greek word barys taken to mean “heavy”. Therefore, the discovery of this element in the atmosphere of an exoplanet, which usually contains lighter elements such as oxygen, carbon and hydrogen, is very interesting and unexpected.

These two extrasolar planets with names WASP-76b And WASP-121b Named, they both fall into the group of super-hot Jupiter planets. While they are about the same size as Jupiter, a giant planet 11 times larger than Earth, their surface temperatures reach over 1,000 degrees Celsius. This high temperature is due to the proximity of these planets to their host stars.

Astronomers are of the opinion that this close distance has caused these planets to have strange western features. For example, in WASP-76b witness a phenomenon called iron rain Are. Therefore, the existence of these phenomena has made them an excellent target for atmospheric observations.

Tomás Azúdo Silva, an astronomer at the University of Porto in Portugal, who is also the main researcher of this study, announced in a statement: “This was actually an accidental discovery and we were not looking for a barium, and considering that nothing like this has ever happened before. It had not been seen in any other exoplanet, we had to check whether this barium was really obtained from the planet or not.”
