Scientists experimentally found that some planets with a large content of carbon can really have a huge diamond layer of the mantle.
Studying the atmosphere and the geological structure of distant worlds, researchers from the University of Arizona and the University of Chicago imitated the conditions of the inner part of carbide exoplanets, which rotate around stars with a higher carbon content than our sun.
To do this, they placed carbide of silicon and water (which is very common in the universe) in cells with diamond anvils, creating high pressure. The scholars were then affected by a laser sample to increase the temperature and control the reaction between substances. In such conditions, silicon carbide entered the reaction with water, turning into diamonds and silica.
As a result, the team concluded that carbon-rich planets cannot maintain sufficient geological activity and their atmosphere is unsuitable for human habitat. Nevertheless, the study will help scientists better interpret the data of the upcoming observation missions for excooplates.
Recall that earlier astronomers discovered the extreme exoplanet, on which they go
