Neutrino Physics Research

Supernova 1987A in the Large Magellanic Cloud was not only the brightest since Keplers supernova in 1604, but also the very first supernova in history which could be studied in all ranges of the electromagnetic spectrum with sensitive instruments based on ground and in space. In addition a flash of neutrinos was observed, confirming observationally the concept of production of neutrinos in the collapse of a star. Of equal importance were detailed theoretical model calculations which had become possible through the new generation of powerful supercomputers. So, SN 1987A is a test case for existing theories and has provided a wealth of new unexpected features. Next to the observation of neutrinos, especially remarkable features of SN 1987A are the bolometric light curve, the detection of infrared and gamma-ray line radiation and the detection of the very high energy X-ray continuum, all connected to the existence and spatial distribution of 0.075 M⊙ of radioactive 56Co in the debris of this stellar collaps.
