M giants with IGRINS : II. Chemical evolution of fluorine at high metallicities
Context. The origin and evolution of fluorine in the Milky Way Galaxy is still under debate. In particular, the increase in the [F/Fe] in metal-rich stars found from near-IR HF lines is challenging to explain theoretically. Chemical evolution models with current knowledge of yields from different fluorine-producing stellar sources cannot reproduce these observations.Aims. The aim of this work is t
