| Massive stars eject the products of their nuclear burning into the interstellar medium via stellar winds and supernova explosion. Chemical yields from single massive stars are widely available in the literature. However, massive stars are often found in binary systems, and the effects of binary interactions on the yields have not been taken into account in most previous studies. With MESA stellar evolution code I have computed massive star models with initial masses from 10 to 80 M⊙, both rotating and non-rotating at solar metallicity (Z=0.014) and their massive non-rotating binary counterparts. I have calculated with wind yields of three short-lived radioactive nuclei that are important for the early Solar System; aluminium-26, chlorine-36, and calcium-41. In this seminar, I will present the results of my PhD research up till now, discuss the wind yields of these isotopes and the processes that impact them, as well as the potential sources of these isotopes in the early Solar System. |
