The gas and dust released eventually contribute to the rare materials of planets, such as Earth. For example, the nuclear astrophysical processes that create Earth’s heavy metals are thought to be the result of the huge amounts of energy produced by the merger of two neutron stars or collisions of neutron stars and black holes. This in turn has implications for our understanding about the origins of heavier elements. This finding could help refine calculations for nuclei with more neutrons. Theoretical studies of neutron-rich nuclei involve extremely complicated calculations, and theoretical physicists have so far only been able to precisely model more stable nuclei with few neutrons. In terms of nuclear theory, the finding provides a vital reference point for tweaking models of neutron-rich nuclei and for assessing their accuracy, explains Kubo. This knowledge in turn informs our understanding of the astrophysical processes that form Earth’s heavier elements. If you made table salt from this super-heavy version of sodium-and the most neutron-rich isotope of chlorine, salt’s other constituent-it would taste and behave like normal salt, except it would be roughly 1.6 times heavier, says nuclear physicist Toshiyuki Kubo.īut far more than being a scientific curiosity, this finding has important implications for theories on the structure of atomic nuclei.
