Web17 de abr. de 2024 · Scientists have inferred that helium hydride was this first, primordial molecule. Once cooling began, hydrogen atoms could interact with helium hydride, leading to the creation of molecular hydrogen — the molecule primarily responsible for the formation of the first stars. WebThe so-called slow neutron-capture process, or s-process, mostly occurs during the late stages in the evolution of stars of 1–10 solar masses ( M⊙ ). But the s-process accounts for the formation of only about half of the isotopes beyond iron.
