- W46125593 abstract "Predictions are given about the temporal and spatial behaviour of the isotopic ratio N/ 15 N in our Galaxy. It is assumed that N is produced in stars of all masses (but the bulk comes from low and intermediate mass stars) as purely secondary element, whereas 15 N originates only from explosive H-burning taking place during nova outbursts. The model of galactic chemical evolution used already reproduces many features of the solar neighbourhood and the galactic disk, such as the gradient of C/ 13 C. It is predicted that N/ 15 N decreases by a factor of ≃1.8 between the epoch of formation of the solar system and now, and that its gradient along the galactic disk (14-4Kpc) is ≃ +6.8 Kpc −1" @default.
