<Fred Hoyle> helped explain the origin of chemical <Elements> through <stellar nucleosynthesis>. The 1957 synthesis paper he coauthored connected stellar conditions, <nuclear reactions> and the observed pattern of elemental abundances.
Different processes operate under different physical conditions. Charged-particle reactions can build progressively heavier nuclei, while <neutron capture> supplies routes to many nuclei beyond the iron group. Comparing reaction timescales with stellar conditions connects laboratory <nuclear physics> to the composition of <stars> and later generations of matter. The account is a synthesis of several production mechanisms, rather than a claim that one stellar reaction makes every <chemical element>.<Synthesis of the Elements in Stars by E. Margaret Burbidge and others>[Sections I–II: abundances, physical processes, sites and timescales of stellar synthesis]{ref}
