Evolved stars with inconsistent age estimates: Abundance outliers or mass transfer products?
Polly Frazer, Emily J. Griffith, David W. Hogg +2
In the Milky Way disk there is a strong trend linking stellar age to surface element abundances. Here we explore this relationship with a dataset of 8,803 red-giant and red-clump s…
Optical Spectroscopy Reveals Hidden Neutron-capture Elemental Abundance Differences among APOGEE-identified Chemical Doppelgängers
Catherine Manea, Melissa Ness, Keith Hawkins +9
Grouping stars by chemical similarity has the potential to reveal the Milky Way's evolutionary history. The APOGEE stellar spectroscopic survey has the resolution and sensitivity f…
Galactic Doppelganger: The chemical similarity among field stars and among stars with a common birth origin
M. Ness, H-W. Rix, David W. Hogg +9
We explore to which extent stars within Galactic disk open clusters resemble each other in the high-dimensional space of their photospheric element abundances, and contrast this wi…
