Fluorine in red giant stars : evidence for nucleosynthesis.
Abstract
Flourine abundances were determined in several K giants and asymptotic giant branch (AGB) stars, using the infrared vibration-rotation lines of HF. The data presented constitute the only available information on the fluorine abundance outside the solar system and provide invaluable clues to the question of the nucleosynthetic origin of F. The observations confirm that F production occurs at a He-burning site and constrain the current models of AGB stars.
