Scientific paper

Galactic chemical evolution models are presented that take into account several recent developments: (1) models of classical novae nucleosynthesis question the total amount of ^7^Li produced by these systems; (2) observations and models for lithium production in asymptotic giant branch stars and the mass of the planetary nebula that they eject; (3) ^7^Li production from ν-process nucleosynthesis in Type II supernova explosions. The best fitting models for the upper envelope of the observed N(Li) as a function of [Fe/H] suggest that Type II supernovae and intermediate-low mass stars each produce about 1/2 of the solar lithium abundance, although fractions between 1/4 to 3/4 for each source are not conclusively ruled out. The variance of these fractions primarily reflect the uncertainties in the input nucleosynthesis.
