Timeline of white dwarfs, neutron stars, and supernovae

Note that this list is mainly about the development of knowledge, but also
about some supernovae taking place.

   * 1006 - The brightest (magnitude -9m)recorded supernova is observed in
     the constellation of Lupus
   * 1054 - Chinese and American Indian astronomers observe the Crab
     supernova explosion,
   * 1572 - Tycho Brahe discovers his supernova in Cassiopeia,
   * 1604 - Johannes Kepler's supernova in Serpens is observed,
   * 1862 - Alvan Clark observes Sirius B,
   * 1866 - William Huggins studies the spectrum of a nova and discovers
     that it is surrounded by a cloud of hydrogen,
   * 1885 - A supernova is observed in the Andromeda Galaxy leading to
     recognition of supernovae as a distinct class of novae
   * 1914 - Walter Adams determines an incredibly high density for Sirius B,
   * 1926 - Ralph Fowler uses Fermi-Dirac statistics to explain white dwarf
     stars,
   * 1930 - Subrahmanyan Chandrasekhar discovers the white dwarf maximum
     mass limit,
   * 1933 - Fritz Zwicky and Walter Baade propose the neutron star idea and
     suggest that supernovae might be created by the collapse of normal
     stars to neutron stars---they also point out that such events can
     explain the cosmic ray background,
   * 1939 - Robert Oppenheimer and George Volkoff calculate the first
     neutron star models,
   * 1942 - J.J.L. Duyvendak, Nicholas Mayall, and Jan Oort deduce that the
     Crab Nebula is a remnant of the 1054 supernova observed by Chinese
     astronomers,
   * 1958 - Evry Schatzman, Kent Harrison, Masami Wakano, and John Wheeler
     show that white dwarfs are unstable to inverse beta decay,
   * 1962 - Riccardo Giacconi, Herbert Gursky, Frank Paolini, and Bruno
     Rossi discover Sco X-1,
   * 1967 - Jocelyn Bell and Anthony Hewish discover radio pulses from a
     pulsar,
   * 1967 - J.R. Harries, Ken McCracken, R.J. Francey, and A.G. Fenton
     discover the first X-ray transient (Cen X-2),
   * 1968 - Thomas Gold proposes that pulsars are rotating neutron stars,
   * 1969 - David Staelin, E.C. Reifenstein, William Cocke, Mike Disney, and
     Donald Taylor discover the Crab Nebula pulsar thus connecting
     supernovae, neutron stars, and pulsars,
   * 1971 - Riccardo Giacconi, Herbert Gursky, Ed Kellogg, R. Levinson, E.
     Schreier, and H. Tananbaum discover 4.8 second X-ray pulsations from
     Cen X-3,
   * 1974 - Russell Hulse and Joseph Taylor discover the binary pulsar
     PSR1913+16,
   * 1977 - Kip Thorne and Anna Zytkow present a detailed analysis of
     Thorne-Zytkow objects,
   * 1982 - D.C. Backer, Shrinivas Kulkarni, Carl Heiles, M.M. Davis, and
     Miller Goss discover the millisecond pulsar PSR1937+214,
   * 1985 - Michiel van der Klis discovers 30 Hz quasi-periodic oscillations
     in GX 5-1,
   * 1987 - Ian Shelton discovers Supernova 1987a in the Large Magellanic
     Cloud ...
