The astrophysical origins of the element fluorine remain uncertain due in part to the availability of only a small number of abundance results for this element, that has observable transitions only in the infrared. We discuss fluorine abundances for a sample of five red-giants in the Galactic globular cluster ω Centauri. These abundances are derived from vibration-rotation transitions of...
Oxygen abundances are derived in a sample of field F and G dwarfs, for which boron abundances have been determined from HST spectra. The metallicities of the program stars span the range of [Fe/H]=-0.75 to +0.15. The weak [O I] λ6300 Å and O I λ6158 Å lines have been used for the oxygen abundance analysis. In addition, the strong near-IR triplet O I lines have been analyzed and these lines tend to...
