Caltech with the work far from complete, and encouraged the Burbidges to join him in California. Both of the Burbidges had temporary positions created for them in 1956 at Caltech by Fowler for this purpose. The first complete draft was completed by the Burbidges in 1956 at Caltech, after adding extensive astronomical observations and experimental data to support the theory. Margaret Burbidge, the paper's
405:, for example, argued in 2008 that "Hoyle should have been awarded a Nobel Prize for this and other work". He also speculated that the reason why Hoyle ended up empty-handed was that "Fowler was believed to be the leader of the group." Burbidge insisted that this perception was false and pointed to Hoyle's earlier foundational papers from 1946 and 1954. 201:. However, it went beyond simply reviewing Hoyle's work, by incorporating observational measurements of elemental abundances published by the Burbidges, and Fowler's laboratory experiments on nuclear reactions. The result was a synthesis of theory and observation, which provided convincing evidence for Hoyle's hypothesis. 332:

Some have presumed that Fowler was the leader of the group because the writing and submission for publication were done at Caltech in 1956, but Geoffrey Burbidge has stated that this is a misconception. Fowler, though an accomplished nuclear physicist, was still learning Hoyle's theory in 1955 and
