question: The BFH paper, named after the initials of the authors of the paper, a landmark paper of stellar physics published in "Reviews of Modern Physics" in which year?
answer: 1957
context: Title: Margaret Burbidge
  Passage: Eleanor Margaret Burbidge ("née" Peachey), FRS (born August 12, 1919 in Davenport) is a British-born American astrophysicist, noted for original research and holding many administrative posts, including Director of the Royal Greenwich Observatory.
  Title: Neutron capture nucleosynthesis
  Passage: Neutron capture nucleosynthesis describes two nucleosynthesis pathways: the r-process and the s-process, for "rapid" and "slow" neutron captures, respectively.  R-process describes neutron capture in a region of high neutron flux, such as during supernova nucleosynthesis after core-collapse, and yields neutron-rich nuclides.  S-process describes neutron capture that is slow relative to the rate of beta decay, as for stellar nucleosynthesis in some stars, and yields nuclei with stable nuclear shells.  Each process is responsible for roughly half of the observed abundances of elements heavier than iron.  The importance of neutron capture to the observed abundance of the chemical elements was first described in 1957 in the BFH paper.
  Title: B2FH paper
  Passage: The BFH paper, named after the initials of the authors of the paper, Margaret Burbidge, Geoffrey Burbidge, William Fowler, and Fred Hoyle, is a landmark paper of stellar physics published in "Reviews of Modern Physics" in 1957.  The formal title of the paper is "Synthesis of the Elements in Stars", but the article is generally referred to only as "BFH".
