Theoretical prediction of the neutrino
burst versus the neutrino signal as detected from
SN 1987A by KamiokaNDE II 23 February 1987
For the antineutrino energies ? 20 Mev there is a
strong correlation of e with the direction to
SN1987 in disagreement with the above reaction. A
great puzzle cannot be resolved in a standard
model

Theory Before and After SN 1987A
Before
Hydrodynamic models of supernova light curves
(19641987)
? dynamical and radiative properties of the SN
envelopes ? physics of the plateau light curve
phase (cooling recombination wave) ? physics
of the shock wave breakout ? possible importance
of radioactivities (56Ni) ? crucial role of
presupernova radius (red supergiant vs blue
supergiant)
Hydrodynamic models of gravitational collapse of
stellar cores (1967 1987)
? Crucial role of Fe decomposition ? Physics of
the neutrino transport (neutrino heat
conductivity) ? supernova explosion mechanism
no explosion in spherical symmetry,
importance of rotation and magnetic feeld
Constructing of evolutionary presupernova models
(1964 1987)
22
Main issues of SN 1987 A
? Detection of the neutrino signal ?
Unprecedentedly detailed multi-wavelength
spectra light curves ? First detection and
measuring of radioactive Ni ? Importance of large
scale mixing of composition ? First detailed
structure of medium around the presupernova
(rings, light echo, interaction between RSG and
BSG winds)
After
New era in supernova study all over the World
! (10 accuracy vs factor of 2 before SN 1987A)
