Supernova remnants (SNRs):
* Feb. 23, 1987, in LMC
* Neutrinos were detected by Kamiokande (12 events) and IMB (8 events) 3 hours ahead of optical brightening up.
* γ-ray lines from radioactive nuclei are detected.
- According to the spectrum
with H = SN II
without H = SN I
with Si = SN Ia
without Si but with He = SN Ib
without Si and without He = SN Ic
- SN Ia as a standard candle to determine distances
- The energy source for SN Ia is nuclear, and for the others is gravitational
