Abundance ratio [F/O] as a function of [O/H] in the solar neighborhood for the one-infall (left panel) and two-infall (right panel) chemical evolution models taking into account the effects of the novae. We consider for fluorine themaximum yield by José & Hernanz (1998; model ONe7) related to ONe white dwarf with masses of 1.35 M_⊙. The blue line indicates the reference F7 model. The model with the “maximum” F novae yield is labeled with the pink line. Models with “maximum” F nova yield multiplied by factor of 5 and 10 are shown with orange and purple lines, respectively.
