Description
| - We show that hot first stars do not have any wind driven purely by hydrogen or helium. However, during the evolution of these stars the CNO elements may emerge on their surfaces due to the mixing processes. Contrary to hydrogen and helium, these elements are able to drive a stellar wind. Consequently, evolved first stars may have winds driven purely by CNO elements. We study the properties of such stellar winds for different abundance of CNO elements and discuss their influence on the surrounding environment. We show that CNO driven winds exist in more luminuous stars. Moreover, for very hot stars CNO elements are too much ionized to drive a wind. In most cases the derived mass-loss rate is smaller than that calculated with solar mixture of elements. This is connected with the fact that in the present hot stars heavier elements (as iron) are the most important element that influence the wind mass-loss rate.
