Baade and Zwicky propose supernovae and neutron stars

node

Two papers in the Proceedings of the National Academy of Sciences introduced the term super-nova for a distinct and far more energetic class of stellar explosion, proposed that such events are the transition of an ordinary star into a star composed of closely packed neutrons, and connected them to cosmic rays. The neutron had been identified only two years earlier. The proposal was almost entirely theoretical and went without observational support for thirty-three years.

A node is not a place. Drawing it on a map would assert something about the world that no stored fact supports.

  37. Introduces the term super-nova, proposes the transition of an ordinary star into a star of closely packed neutrons, and links such events to cosmic rays. Volume and page numbers are deliberately not asserted because they were not confirmed; the content is known through a later PNAS retrospective read via search summary.
