Fluorine in the solar neighborhood - is it all produced in AGB-stars?

H. Jönsson, N. Ryde, G. M. Harper +2

The origin of 'cosmic' fluorine is uncertain, but there are three proposed production sites/mechanisms: AGB stars, $ν$ nucleosynthesis in Type II supernovae, and/or the winds of Wo…

Hyperfine dependent $g f$ -values of Mn I lines in the 1.49 $-$ 1.80 $μ$ m H-band

Martin Andersson, Jon Grumer, Nils Ryde +5

The three Mn I lines at 17325, 17339 and 17349 Å~are among the 25 strongest lines ( $lo g (g f) > 0.5$ ) in the H-band. They are all heavily broadened due to hyperfine structure and the…

The Chemical Evolution of Fluorine in the Bulge - High-resolution K-band spectra of giants in three fields

H. Jönsson, N. Ryde, G. M. Harper +6

Possible main formation sites of F in the Universe include AGB stars, the ν-process in Type II SNe, and/or W-R stars. The importance of the W-R stars has theoretically been questio…
