  9. NGC 2397

  10. NGC 6946 SN 1917A, SN 1939C, SN 1948B, SN 1968D, SN 1969P, SN 1980K, SN 2002hh, SN 2004et, and SN 2008S SN 2002hh SN 2004et

  11. Signatures of dust formation in SNe • Asymmetric Emission Lines • IR emission • Fading in Visible • Increased extinction • Molecular formation

  12. SN 2003gd Mdust = 0.02 M☉

  13. SN 2002hh

  14. SN 2007od SN 2007it

  15. AG Car Hα Radio

  16. Mdust = 10-6 Mo SN 1987A 11.7 micron (red) + F625W (yellow) (Bouchet et al. 2006)

  17. CSM Interaction

  18. <-- M = 8 - 40 M☉ M = 1.4 - 25 M☉ -->

  19. Mass loss = 10 Mo Mgas/Mdust =100 Mgas = 9.9 M☉ Mdust = 0.1 M☉
