Definition

In the astrophysical context, a heavy element is any element heavier than helium. The term “metal” is also used by astronomers. The definition stems from the fact that only helium and hydrogen (and small quantities of lithium and beryllium) were produced in the few first minutes after the big bang: all other elements were produced afterward, through stellar processing (nuclear reactions or supernovae).
