Abstract

For ¹²C and ¹⁶O, rotating models predict in general enhanced yields. At high metallicity, the carbon and oxygen yields from the very high mass stars, which go through a WR phase, are little affected by rotation. For ¹⁴N, rotation allows the production of important amounts of primary nitrogen in \it intermediate mass stars at very low metallicity. The process invoked for this production is different, from the classically accepted scenario \it i.e. the Hot Bottom Burning (HBB) in Asymptotic Giant Branch (AGB) stars. Rotating models also predict important productions of primary ¹³C, ¹⁷O and ²²Ne at very low metallicity.
