Measuring chemical likeness of stars with RSCA
Damien de Mijolla, Melissa K. Ness
Identification of chemically similar stars using elemental abundances is core to many pursuits within Galactic archaeology. However, measuring the chemical likeness of stars using…
The COMBS Survey -- III. The Chemodynamical Origins of Metal-Poor Bulge Stars
Madeline Lucey, Keith Hawkins, Melissa Ness +6
The characteristics of the stellar populations in the Galactic Bulge inform and constrain the Milky Way's formation and evolution. The metal-poor population is particularly importa…
A2A: 21,000 bulge stars from the ARGOS survey with stellar parameters on the APOGEE scale
S. M. Wylie, O. E. Gerhard, M. K. Ness +3
We use the data-driven method, The Cannon, to bring 21,000 stars from the ARGOS bulge survey, including 10,000 red clump stars, onto the parameter and abundance scales of the cross…
The challenge of simultaneously matching the observed diversity of chemical abundance patterns in cosmological hydrodynamical simulations
Tobias Buck, Jan Rybizki, Sven Buder +5
With the advent of large spectroscopic surveys the amount of high quality chemo-dynamical data in the Milky Way (MW) increased tremendously. Accurately and correctly capturing and…
Orbital Torus Imaging: Using Element Abundances to Map Orbits and Mass in the Milky Way
Adrian M. Price-Whelan, David W. Hogg, Kathryn V. Johnston +9
Many approaches to galaxy dynamics assume that the gravitational potential is simple and the distribution function is time-invariant. Under these assumptions there are traditional…
Mapping the tilt of the Milky Way bulge velocity ellipsoids with ARGOS and DR2
Iulia T. Simion, Juntai Shen, Sergey E. Koposov +4
Until the recent advent of Data Release 2 (DR2) and deep multi-object spectroscopy, it has been difficult to obtain 6-D phase space information for large numbers of stars be…
