Metallicity and -element Abundance Gradients along the Sagittarius Stream as Seen by APOGEE

Christian R. Hayes, Steven R. Majewski, Sten Hasselquist +27

Using 3D positions and kinematics of stars relative to the Sagittarius (Sgr) orbital plane and angular momentum, we identify 166 Sgr stream members observed by the Apache Point Obs…

Modeling Dust and Starlight in Galaxies Observed by Spitzer and Herschel: The KINGFISH Sample

G. Aniano, B. T. Draine, L. K. Hunt +30

Dust and starlight are modeled for the KINGFISH project galaxies. With data from 3.6 micron to 500 micron, models are strongly constrained. For each pixel in each galaxy we estimat…

Geometric properties of galactic discs with clumpy episodes

Leandro Beraldo e Silva, Victor P. Debattista, Tigran Khachaturyants +1

A scenario for the formation of the bi-modality in the chemical space [/Fe] vs [Fe/H] of the Milky Way was recently proposed in which -enhanced stars are produced early and q…
