Astronomers concluded about the effect of high temperatures on the composition of stars and planets

The researchers analyzed the temperature distribution across the disk during evolution and came to the conclusion that

sequence of mineral condensation.The core heats up to its maximum at the end of collapse, several hundred thousand years into the evolutionary process. Scientists have found that although the composition of the star is similar to the composition of the core of its molecular cloud, the star nevertheless has much less refractory elements (aluminum) in its composition than in the core. But in cloud cores with the highest temperatures, aluminum is present in the composition.

Stars and planets are formed from the samematerial, so their chemical composition should be identical, but the compositions of the planets also do not completely coincide with the compositions of stars. Astronomers believe that this is due to the formation of planets as a result of the merger of already condensed mineral dust.

Scientists also analyze meteorites of varioustypes to determine their chemical composition. Since different minerals in stars and planets condense under different conditions, at different times and in different places, this makes it difficult to understand the general chemistry of the planets.
