The stellar origin of Li-7 - Do AGB stars contribute a substantial fraction of the local Galactic lithium abundance?

We adopt up-to-date Li-7 yields from asymptotic giant branch stars in order to study the temporal evolution of Li-7 in the solar neighbourhood in the context of a revised version of the two-infall model for the chemical evolu tion of our galaxy. We consider several lithium stellar sources besides the asymptotic giant branch stars such as type II supernovae, novae, low-mass giants as well as Galactic cosmic rays and low-mass X-ray binaries. We conc lude that asymptotic giant branch stars cannot be considered as important L i-7 producers as believed so far and that the contribution of low-mass gian ts and novae is necessary to reproduce the steep rise of the Li-7 abundance in disk stars as well as the meteoritic Li-7 abundance. Lithium production in low-mass X-ray binaries hardly affects the temporal evolution of Li-7 i n the solar neighbourhood.
