On the cosmic origin of Fluorine
  The cosmic origin of fluorine, the ninth element of the Periodic Table, is
still under debate. The reason for this fact is the large difficulties in
observing stellar diagnostic lines, which can be used for the determination of
the fluorine abundance in stars. Here we discuss some recent work on the
chemical evolution of fluorine in the Milky Way and discuss the main
contributors to the cosmic budget of fluorine.
