Title: Astronomy seminar - Lithium in the Galaxy: To Be or not to Be

Abstract:
The astronomical community’s interest in Li continues to be vastly 
disproportional to its small abundance. The Li content of stars in the 
Galaxy links together several different research fields; from cosmology 
and Big Bang nucleosynthesis, to cosmic ray spallation in the 
interstellar medium, to mixing processes in stellar interiors, and even 
the presence of exoplanets. I will describe the intricate abundance 
patterns found for stars in different evolutionary phases and how the 
fragile nature of this light element makes it an excellent diagnostic 
tool for late-type stellar evolution all they way from the pre-main 
sequence to the tip of the asymptotic giant branch. I will further 
discuss some famous problems related to Li production and depletion and 
potential solutions in the light of improved models of stars and their 
spectra.

Jaime de la Cruz Rodriguez will host the seminar.
