Abstract
The abundance of Lithium observed in very young stellar populations is ~ 4 times larger than the primordial one estimated by recent Planck measurements. Since Lithium is easily destroyed in stellar interiors, the search for astrophysical sources responsible for the observed Lithium over-abundance was a mystery for decades. In this seminar I'll discuss the detection of Lithium in the early spectra of the slow nova V1369 Cen, which can solve this problem, and then I'll discuss the consequences for the chemical evolution in the Galaxy.
