The study of chemical abundances in the interstellar medium and stars in our Galaxy is of utmost importance, as it provides insights into the chemical enrichment of the galactic interstellar medium by massive stars and the evolution of different components of the Milky Way. Lithium is frequently the subject of spectroscopic surveys and studies aimed at determining its abundance in

In astrophysics, there are elements that provide important diagnostics used in various fields, such as Lithium. For instance, measurements of Lithium abundances are important in cosmology where there is a well-known problem of matching the measured abundances in population II stars with those predicted by cosmological models of Big Bang synthesis. Measurements of Lithium abundances are also essential for understanding

The chemical history of Lithium abundance in the Universe is very complex. This chemical element has been first produced during the Big Bang, even if in very small quantities compared with hydrogen and helium. Since then, lithium is continuously created and destroyed by several processes occurring in stellar interior. This means that the lithium abundances we observe in stars today
