The Pristine survey XIII: Uncovering the very metal-poor tail of the thin disc
Emma Fernández-Alvar, Georges Kordopatis, Vanessa Hill +9
We evaluate the rotational velocity of stars observed by the Pristine survey towards the Galactic anticentre, spanning a wide range of metallicities from the extremely metal-poor r…
The AMBRE Project: Origin and evolution of sulfur in the Milky Way
J. Perdigon, P. de Laverny, A. Recio-Blanco +4
Sulfur is a volatile chemical element that plays an important role in tracing the chemical evolution of galaxies. However, its nucleosynthesis origin and abundance variations are s…
The assembly history of the Galactic inner halo inferred from alpha-patterns
Emma Fernández-Alvar, Patricia B. Tissera, Leticia Carigi +3
We explore the origin of the observed decline in [O/Fe] (and [Mg/Fe]) with Galactocentric distance for high-metallicity stars ([Fe/H] > -1.1), based on a sample of halo stars selec…
Disentangling the Galactic Halo with APOGEE: II. Chemical and Star Formation Histories for the Two Distinct Populations
Emma Fernández-Alvar, Leticia Carigi, William J. Schuster +13
The formation processes that led to the current Galactic stellar halo are still under debate. Previous studies have provided evidence for different stellar populations in terms of…
Disentangling the Galactic Halo with APOGEE: I. Chemical and Kinematical Investigation of Distinct Metal-Poor Populations
Christian R. Hayes, Steven R. Majewski, Matthew Shetrone +21
We find two chemically distinct populations separated relatively cleanly in the [Fe/H] - [Mg/Fe] plane, but also distinguished in other chemical planes, among metal-poor stars (pri…
Atypical Mg-poor Milky Way field stars with globular cluster second-generation like chemical patterns
J. G. Fernández-Trincado, O. Zamora, D. A. Garcia-Hernandez +48
We report the peculiar chemical abundance patterns of eleven atypical Milky Way (MW) field red giant stars observed by the Apache Point Observatory Galactic Evolution Experiment (A…
