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

Mass loss = 10 M☉
Mgas/Mdust =200
Mgas = 9.95 M☉
Mdust = 0.05 M☉
So, Mdust = 0.4 – 0.7 M☉
Mgas = 80 to 140 M☉

• Is there accretion of dust in the ISM?
• When do AGB stars become important dust makers?
• Why does SN 1987A always have to be different?
• Do SNe with significant CSM make more dust?
• Do SNe destroy more dust than they make?
