How much iron can each type I supernova produce
Abstract
If each intermediate-mass star were to eject a Chandrasekhar mass of Ni-56, the resulting iron abundance in the Galaxy would be much greater than observed. The strength of this argument is reviewed. Attention is given to an estimate of iron abundance, constraints on the ejected mass of iron, and the net star formation rate. It is found that current estimates favor limits less than 0.2 solar mass for the amount of iron which can be produced by each SNI, but it is not possible to rule out substantially larger values, even up to a Chandrasekhar mass.
