On Earth, precious stones are a relative rarity and in most of them they are deeply underground. But space is a real treasure. Astronomers have found a new class of planets, containing many elements, composed of sapphires and rubies, it is possible that they can shine. Science Alert writes about it.
These planets are a type of dense planets like the Earth and Mars, with a high proportion of stones, metals or their combinations, but much larger (but nevertheless smaller than Neptune). However, this group, as a rule, revolves around its stars much, much closer than Earth or even most 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 can mean the presence of rubies and sapphires. Researchers from the University of Zurich in Switzerland and Cambridge in the UK have identified three planets that could be listed in such an interesting type. orbit only 3 days; 55 Cancri e, at a distance of 41 light-years, with an orbit of only 18 hours; and WASP-47 e, located at 870 light-years, with an orbit of 18 hours also.
Planets consist of dusts and residual gases flowing around an emerging star. Electrostatic forces begin to trap dust particles and gases, rotating around the star, in the breast; Little by little, they accumulate so much that they do not have enough gravity to attract even larger particles, and if all goes away, the mass from which the planet is formed will become
. and magnesium, and this, according to planet scientist scientists, leads to compositions such as Mercury, Venus, Earth and Mars.
But when you approach the star, there is of course a lot, a lot warmer. Thus, any planet born in this way will not look like the Earth.
"Many elements are still in the gas phase and the planetary building blocks have a completely different composition," says astrophysicist Caroline Dorn of the University of Zurich.
She and her team performed simulations and discovered that with silicon and magnesium, aluminum and calcium are the most common components. There is almost no iron at this place.
Planetary magnetic fields are generated by a liquid conducting core which, at least in theory, should not be iron. But, according to the simulation of the team, these planets would have no nuclei at all and therefore would not have magnetic fields, or at least magnetic fields, which looked nothing like those discovered around the planets of the system. solar. It would be completely different, and so the weather conditions and the cooling would also be different.
"What's interesting is that these objects are completely different from most planets similar to the Earth," Dorn said.
Density these planets are much smaller. Since their orbits are very close to their stars. For example, some of them can "spread" in the form of sapphire or diamond.
