J. Robert Oppenheimer (born Julius Robert Oppenheimer; / ˈ ɒ p ən h aɪ m ər / OP-ən-hy-mər; April 22, 1904 – February 18, 1967) was an American theoretical physicist who served as the director of the Manhattan Project's Los Alamos Laboratory during World War II.
Rebecca Oppenheimer is an American astrophysicist and one of four curator/professors in the Department of Astrophysics at the American Museum of Natural History (AMNH) on Manhattan's Upper West Side. Oppenheimer is a comparative exoplanetary scientist. She investigates planets orbiting stars other than the Sun.
Oppenheimer and Snyder did, however, refer to an earlier article by Oppenheimer and Volkoff on neutron stars, improving upon the work of Lev Davidovich Landau. [7] Previously, and in the same year, Oppenheimer and three colleagues, Richard Tolman , Robert Serber , and George Volkoff , had investigated the stability of neutron stars, obtaining ...
The Tolman–Oppenheimer–Volkoff limit (or TOV limit) is an upper bound to the mass of cold, non-rotating neutron stars, analogous to the Chandrasekhar limit for white dwarf stars. Stars more massive than the TOV limit collapse into a black hole .
1939 – Robert Serber, George Volkoff, Richard Tolman, and J. Robert Oppenheimer study the stability of neutron stars, obtaining the Tolman–Oppenheimer–Volkoff limit. [115] [116] [114] 1939 – J. Robert Oppenheimer and Hartland Snyder publish the Oppenheimer-Snyder model for the continued gravitational contraction of a star. [117] [114] [118]
[Before World War II] Oppenheimer’s reputation and influence were centered around the small and close circle of physicists. As the wartime director of Los Alamos Laboratory, he was bound to receive important public attention, but there were other directors of great laboratories, and other physicists, who shared equal esteem but did not become objects of such general interest.
Oppenheimer as educated at Cheltenham Ladies' College before earning a scholarship to Lady Margaret Hall Oxford University, where she studied philosophy, politics, and economics, graduating with first-class honors. [1] [2] At Oxford, she met Sir Michael Oppenheimer, a baronet from a South African mining family, whom she married in 1947. [2]
