Stellar mass loss and galactic chemical evolution
Published online by Cambridge University Press: 12 April 2016
Extract
We summarize here some of the results that we have obtained from chemical evolution models. In particular, we discuss those aspects related to stellar mass loss, helium production, a varying heavy element yield and the very light stars.
The observed value of the helium to heavy element abundance ratio ΔY/ΔZ is about 3 (e.g. Lequeux et al. 1979). First theoretical estimates gave ΔY/ΔZ= 0.4 (Hacyan et al. 1976).
