ON MASSIVE NEUTRON CORES. Physical Review Vol. 55, February 15, 1939. Printed in USA. (Received January 3, 1939.) Pp. 374-381. Original staples, just beginning to loosen at edges, otherwise near fine. Signed Warmly [underlined], Oppy. The true separate offprint paginated and printed so the first page, 374, is a recto and other page number s set at appropriate edges instead of centered. Leaves folded folded and stapled at gutter to form a pamphlet. Effectively predicts neutron stars and that, if massive enough, the stellar matter will contract indefinitely. The foundation paper explaining and predicting black holes and the subsequent discoveries and revolutions in astrophysics. Excessively rare, no copies recorded of this separate printing. The publication "On Massive Neutron Cores" by J. Robert Oppenheimer and George M. Volkoff, was published in the Physical Review, Volume 55, on February 15, 1939. The paper is a significant contribution to the field of astrophysics and nuclear physics, particularly in the study of neutron stars. Neutron stars are extremely dense celestial objects that are formed from the remnants of massive stars undergoing supernova explosions. This paper by Oppenheimer and Volkoff explores the theoretical aspects of neutron stars, considering the conditions under which a massive neutron core could exist. The work involves applying the principles of general relativity to understand the structure and properties of such dense cores. J. Robert Oppenheimer is a well-known physicist who later played a crucial role in the development of the atomic bomb during World War II as the scientific director of the Manhattan Project. George M. Volkoff, his collaborator in this paper, was a student of Oppenheimer s at Berkeley. This publication is part of the early scientific exploration of neutron stars and contributes to our understanding of the extreme conditions within these objects. It laid the groundwork for subsequent research in astrophysics and continues to be cited in discussions related to neutron stars and compact stellar remnants. Item ID#0586
