"We determined the distribution of velocities in the innermost material ejections of the supernova 1987A, " explains Kjær. Accordingly, the detonation hurled the material at 100 million kilometers per hour to the outside. This corresponds to one tenth of the speed of light or 100, 000 times the speed of a passenger aircraft. However, the material took ten years to reach the outer ring of gas and dust that the star had ejected before his death. "Another material wave inside the supernova is still being heated up by radioactive elements, " the scientists report. This ejecta material is currently spreading at a speed of around 10 million kilometers per hour.
How exactly a supernova is formed, the astronomers do not know, but previous computer models of supernovae had already explained an asymmetric course for likely. The current observations of the Supernova 1987A in the 3-D model directly confirm this assumption for the first time. A prerequisite for 3-D reconstruction was the SINFONI (Spectrograph for Integral Field Observations in the Near Infrared) instrument, which uses so-called integral field spectroscopy to generate spatially resolved spectra, allowing scientists to simultaneously observe different areas in the chaotic central region of the supernova.Press releases of the Max Planck Institute for Astronomy, Heidelberg and the European Southern Observatory ESO (European Southern Observatory), Garching Karina Kjær (Queen's University Belfast, Northern Ireland) et al .: Astronomy and Astrophysics, No. 519 ddp / science.de ?
