The Milky Way’s bulge star formation history as constrained from its bimodal chemical abundance distribution
The Milky Way’s bulge star formation history as constrained from its bimodal chemical abundance distribution
We conduct a quantitative analysis of the star formation history (SFH) of the Milky Way's bulge by exploiting the constraining power of its stellar [Fe/H] and [Mg/Fe] distribution functions. Using APOGEE data, we confirm the previously-established bimodal [Mg/Fe]--[Fe/H] distribution within 3 kpc of the inner Galaxy. Compared to that in …
