AGB:

Mmin 0.8 (depend on Z) Mmax 8

Z = Sum mi/M fraction de masse des elts > He

mixing -> chgmt de composition de la surface AGB enveloppe est expulsee par des vent faibles : composition: H+He burning --> 12C

	  Heavy elts : S elements (slow neutron capture)

(on a la perte de masse totale)

2. atomic mass of the species i
3. nett yield (Msun) Eq: (3) pas claire...
4. mass of species i lost in the wind (Msun) ok mass(i)_lost
5. mass of species i initially present in the wind (Msun) ?? mass(i)_0
6. the average abundance of species i in the wind (mass fraction)
7. initial mass fraction of species i (mass fraction)
8. production factor, f = log10( average abundance of i / initial abundance )

cescutti : yields = ( the total ejected - the already present in the star)
