The Physics of Supernovae




Supernovae are one of the most energetic explosive events in Nature

  • Supernovae are one of the most energetic explosive events in Nature

  • BRIGHT

  • A SN in 10 sec releases 100 times the energy that the sun releases in all its life

  • SN1054 was as luminous as the moon for some days

  • RARE: About 1 per century in our Galaxy

  • Last recorded seen by naked-eye :1006 (Lupus), 1054 (Chinese), 1572 (Brahe), 1604(Kepler)

  • BRIEF: Luminosity falls by a factor of 100 in

  • 4 months
