Evidence of early enrichment of the galactic disk by large-scale winds

Tsujimoto, Takuji; Bland-Hawthorn, Joss; Freeman, Kenneth

Description

Large-scale homogeneous surveys of Galactic stars may indicate that the elemental abundance gradient evolves with cosmic time, which is a phenomenon that was not foreseen in existing models of Galactic chemical evolution (GCE). If this phenomenon is confirmed in future studies, we can show that this effect, at least in part, is due to large-scale winds that once enriched the disk. These set up a steep abundance gradient in the inner disk (RGC ≲ 14 kpc). At the close of the wind phase, chemical...[Show more]
