The rings themselves are regions of high gas density in the star's stellar wind that were flash-ionized by ultraviolet radiation from the supernova. SHINE BRIGHT Supernova 1987A shone as a brilliant point of light near the Tarantula Nebula (pink cloud) in the Large Magellanic Cloud, as pictured from an observatory in Chile.. ESO Available through the VizieR service. The most important aspect of the axisymmetric remnant, however, is that it supports the belief that the star Sk -69° 202 was either spinning rapidly or was orbiting a companion star. https://doi.org/10.1146/annurev.aa.27.090189.003213, W. David Arnett, John N. Bahcall, Robert P. Kirshner, and Stanford E. Woosley, My life has been an interesting voyage. Figure 21: Illustrative examples of feedback effects at work. : That was the first supernova in our local group since the Kepler supernova … Das chilenische Las Campanas Observatorium, wo der Astronom Ian Shelton die Supernova 1987A vor dreißig Jahren erstmalig beobachtete. Figure 2: The distribution of galaxies in the SDSS main galaxy sample on the plane of stellar mass versus specific star-formation rate (sSFR = SFR/M∗). Darauf lässt sich ein Supermarkt bauen, oder das Grundstück in Aktien eintauschen. SN 1987A is not the only supernova with a previously-observed star. SN 1987A war also keine klassische Typ-II-Supernova, wofür auch ihre Helligkeit spricht: Sie erreichte nur ein Zehntel der Leuchtkraft einer typischen Supernova. Furthermore, it is an essential reference standard against which the elemental contents of ...Read More. In the slides above, Supernova 1987A is displayed in three images to show changes over time and allow comparison of what each type of light shows: At top left is the visible light view and at bottom left is the X-ray light image. Supernova 1987A. Figure 13: A collection of estimates of the distribution of mass across the local black hole population (i.e., the local black hole mass function scaled by black hole mass) taken from Shankar et al. Supernova 1987A was a supernova detected on February 24th, 1987, and study of the event has provided modern astronomers with great insight into supernovae. All X-ray images from Chandra X-ray Observatory: NASA/CXC/SAO/PSU/K. [5]  These rings are dense regions in the stellar wind that were ionized by ultraviolet radiation from the supernova.

Wahl in Amerika SN 1987A was observed with ground-based and space-based instruments, as well as with neutrino detectors buried deep under the Earth.

Annual Review of Astronomy and Astrophysics, Vol. Auch im fernen Australien war der „neue“ Stern zu sehen, zuerst erblickte ihn dort der Amateurastronom Albert Jones. 27:629-700 (Volume publication date September 1989) Zu sehen war sie allerdings nur von der Südhalbkugel der Erde, und seither hat keine Supernova mehr für eine solch eindrucksvolle Erscheinung am irdischen Himmel gesorgt.

The three red rings are locate in space as though they lie on a tilted hourglass, with the smallest ring at the narrowest point of the hourglass, and the two larger rings at either end of the hourglass. Courtesy NASA and P. Challis (Harvard-Smithsonian Center for Astrophysics). 1987A was a type II supernova, characterized by the presence of hydrogen in its spectra. : Photo: Abbie Rowe. Bild: Nasa. Because of its high luminosity, it was regularly observed, with the last observation occurring about 5 hours before a neutrino burst released by the supernova arrived at Earth.
