The AMBRE project: The thick thin disk and thin thick disk of the Milky Way
M. Hayden, A. Recio-Blanco, P. de Laverny +2
We analyze 494 main sequence turnoff and subgiant stars from the AMBRE:HARPS survey. These stars have accurate astrometric information from \textit{Gaia}/DR1, providing reliable ag…
The Gaia-ESO Survey: Churning through the Milky Way
M. R. Hayden, A. Recio-Blanco, P. de Laverny +29
We attempt to determine the relative fraction of stars that have undergone significant radial migration by studying the orbital properties of metal-rich ([Fe/H]) stars within…
Effects of the selection function on metallicity trends in spectroscopic surveys of the Milky Way
G. Nandakumar, M. Schultheis, M. Hayden +3
We investigate here the effect of the selection function on the metallicity distribution function (MDF) and on the vertical metallicity gradient by studying similar lines of sight…
The AMBRE Project: chemical evolution models for the Milky Way thick and thin discs
V. Grisoni, E. Spitoni, F. Matteucci +5
We study the chemical evolution of the thick and thin discs of the Galaxy by comparing detailed chemical evolution models with recent data from the AMBRE Project. The data suggest…
Metallicity Gradient of the Thick Disc Progenitor at High Redshift
D. Kawata, C. Allende Prieto, C. B. Brook +6
We have developed a novel Markov Chain Mote Carlo (MCMC) chemical "painting" technique to explore possible radial and vertical metallicity gradients for the thick disc progenitor.…
The age-metallicity structure of the Milky Way disk
J. Ted Mackereth, Jo Bovy, Ricardo P. Schiavon +11
The measurement of the structure of stellar populations in the Milky Way disk places fundamental constraints on models of galaxy formation and evolution. Previously, the disk's str…
The Gaia-ESO Survey: Exploring the complex nature and origins of the Galactic bulge populations
A. Rojas-Arriagada, A. Recio-Blanco, P. de Laverny +36
Abridged: We used the fourth internal data release of the Gaia-ESO survey to characterize the bulge chemistry, spatial distribution, kinematics, and to compare it chemically with t…
Baade's window with APOGEE: Metallicities, ages and chemical abundances
M. Schultheis, A. Rojas-Arriagada, A. E. García Pérez +23
Baade's window (BW) is one of the most observed Galactic bulge fields in terms of chemical abundances. Due to its low and homogeneous interstellar absorption it is considered as a…
