Scientists in a new study have found out what elements appear in space after the death of stars. The work was carried out by a team of experts led by astrophysicist Chiaki Kobayashi from the University of Hertfordshire.

As a result of the study, its authors managed to create a special periodic table, which is based on the stellar origin of the elements presented there. It turned out that in the knowledge of the scientific world there is a significant gap in the question of where gold comes from. The theme of the origin of certain elements is important not only for the reason that it allows one to estimate the content of stellar matter in the human body, but also because in this way it is possible to gain new knowledge about the process of the evolution of the Universe. The Big Bang, which began the latter, was the source of a number of light elements, including helium and hydrogen. Over time, the death of the luminaries led to the formation of more complex ones, including nitrogen and carbon, as well as some metals, among them gold and iron.
Within the framework of new models created by scientists, it was possible to establish: in outer space, the collision of neutron stars is a rarity, and could not lead to the formation of such an amount of gold that is observed now. Experts admit that the precious metal appears from a special type of supernovae, characterized by strong magnetic fields. White dwarfs can serve as a source of nickel and manganese, and the massive Sun – neon and iridium. Smaller stars leave behind nitrogen and strontium.
