Stellar yields in CNO from rotating stellar models

For ${}^{12}$C and ${}^{16}$O, 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 ${}^{14}$N, 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 ${}^{13}$C, ${}^{17}$O and ${}^{22}$Ne at very low metallicity.
