DESCRIPTION:Speakers: Artem Popov (Moscow State University)\nA number of c
 urrent and future neutrino experiments are devoted to the detection of ast
 rophysical neutrinos. Neutrino interactions with dense matter and strong m
 agnetic fields peculiar to astrophysical environments\, such as supernova 
 explosions\, are expected to cause considerable effects in the neutrino fl
 avour evolution. One of the interesting effects is damping of the neutrino
  oscillations due to the neutrino wave packets separation. We develop the 
 wave packet description of neutrino oscillations in astrophysical environm
 ents. It is shown that the damping of neutrino helicity transitions caused
  by their interactions with a magnetic field can occur during supernova ex
 plosions. We emphasize the difference between Dirac and Majorana neutrinos
 . CP-violating effects are also considered.\n\nBased on:\n[1] A.Popov\, A.
