WebActually, 52 Fe can capture a 4 He to produce 56 Ni but that is the last step in the helium capture chain. Given a neutron flux in a massive star, heavier isotopes can be produced by neutron capture. ... The metallicity is sometimes indicated with a symbol Z and young Population I stars have been found with metallicity as high as Z = .03 . WebStars experience very high mass-loss rates as they climb up the AGB (as high as 10-4 M ⊙ yr-1 in the superwind phase). The mass lost is often observed to be dust rich (Bedijn 1987). These stars are often heavily dust obscured in the optical and emit copiously in the IR; they are often so dusty that their SEDs peak at ~ 10 μm (Bedijn 1987).
