Chemically Tagging the HR 1614 Moving Group

De Silva, Gayandhi; Freeman, Kenneth; Bland-Hawthorn, Joss; Asplund, Martin; Bessell, Michael

Description

We present abundances for a sample of F, G, and K dwarfs of the HR 1614 moving group based on high-resolution, high signal-to-noise ratio spectra from the Anglo-Australian Telescope UCLES instrument. Our sample includes stars from Feltzing and Holmberg, as well as from Eggen. Abundances were derived for Na, Mg, Al, Si, Ca, Mn, Fe, Ni, Zr, Ba, Ce, Nd, and Eu. The α, Fe, and Fe-peak element abundances show a bimodal distribution, with four stars having solar metallicities, while the remaining 14...[Show more]
