Indigestible Supernova Leftovers

There seems to be a mysterious "central compact object" lurking amid the debris of Supernova SN1987A. Prevailing supernova paradigms cannot account for this high density remnant. While some aspects of standard supernova theory were supported by observations made during and since the 1987 explosion, astrophysicists are left with several puzzles in addition to the mystery object itself:

"Other puzzles include the largescale asymmetries observed in the heavy element ejecta (Fe-group line emission), the supernova envelope (optical polarization), and the circumstellar medium ([O III] ring), which are in addition to the complex structures resulting from hydrodynamic instabilities."

(Chevalier, Roger A.; "Supernova 1987A at Five Years of Age," Nature, 355:691, 1992.)

Quotes

  • "A sourcebook of unexplained phenomena is therefore a valuable addition to a collection of scientific literature. William R. Corliss has provided this in the past with his source books of scientific anomalies in several subjects, and now he has provided it for astronomy. He has done an excellent job of collecting and editing a large amount of material, taken in part from scientific journals and in part from scientific reporting in the popular or semi-scientific press." -- "The Mysterious Universe: A Handbook of Astronomical Anomalies", reviwed by Thomas Gold, Cornell University, in Icarus, vol.41, 1980

  • "An interesting, systematic presentation of unusual weather [..] This book is recommended for a general audience" --"Corliss, William R., Tornados, Dark Days, Anomalous Precipitation, and Related Weather Phenomena, Sourcebook Project, 1983.", revieweed in Choice, September 1983
  • "..the science is necessarily somewhat speculative, but Corliss's symthesis is based on reputable sources." -- "Corliss, William R. (Compiler). Lightning, Auroras, Nocturnal Lights, and Related Luminous Phenomena" reviwed by Joseph M. Moran, Univ. of Wisconsin in Science Books and Films, Sep/Oct 1983

  • "Before opening the book, I set certain standards that a volume which treads into dangerous grounds grounds like this must meet. The author scrupulously met, or even exceeded those standards. Each phenomenon is exhaustively documented, with references to scientific journals [..] and extensive quotations" -- "Book Review: The moon and planets: a catalog of astronomical anomalies", The Sourcebook Project, 1985., Corliss, W. R., Journal of the Royal Astronomical Society of Canada, Vol. 81, no. 1 (1987), p. 24., 02/1987
