These planets are a kind of superconductors – dense planets such as Earth and Mars, but considerably larger
However, instead of the iron core, similar to Earth, they are rich in calcium and aluminum , reports Depo.ua referring to the scientific alert. Gemstones can be relatively rare and hidden in the depths of our planet, but super-lands of a new type tend to revolve around their stars much closer than the Earth or even most of the super-lands . This means that if they are alternated around the place of their education, their composition may be completely different. Instead of an iron core similar to the Earth, they are rich in calcium and aluminum
which could indicate the presence of rubies and sapphires made from mineral corundum, a crystalline form of calcium. alumina.
Researchers from Zurich Universities in Switzerland and the United Kingdom, Cambridge has identified three planets that can have this type of super-terrestrial. It is HD 219134b, located 21 light-years from Earth; 55 Acquisition at a distance of 41 light-years from Earth and WASP-47, far from our planet at 870 light-years. Their nucleus can not create a global magnetic field, otherwise the cooling of such planets is in progress, otherwise the atmosphere behaves in the same way.
"Many elements are still in the gas phase and the planetary building blocks have a completely different composition.What is interesting is that these objects are completely different from most planets similar to the Earth", explains Astrophysicist Caroline Dorn of the University of Zurich.
Scientists have shown that the density of such planets must be 10 to 20% lower than that of the Earth. Because of the proximity of the stars, the temperature on the surface of these planets should be incredibly high and the atmosphere is not present.
