Stellar archaeology with Gaia: the Galactic white dwarf population

, 2015
Gaia will identify several 1e5 white dwarfs, most of which will be in the solar neighborhood at distances of a few hundred parsecs. Ground-based optical follow-up spectroscopy of this sample of stellar remnants is essential to unlock the enormous ...

Galactic archaeology and its application to the galactic center

, 2018
Galactic archaeology deals with dissecting the Milky Way into its various components with the objective to disentangle processes contributing to the Milky Way formation and evolution. This relies on precise estimation of positions, velocities as well as stellar atmosphere properties of individual stars belonging to different stellar populations that ...

The Far Side of the Galactic Bar/Bulge Revealed through Semi-regular Variables

The Astronomical Journal, 2023
The Galactic bulge is critical to our understanding of the Milky Way. However, due to the lack of reliable stellar distances, the structure and kinematics of the bulge/bar beyond the Galactic center have remained largely unexplored.

The Chemical Enrichment of the Milky Way Disk Evaluated Using Conditional Abundances

The Astrophysical Journal, 2023
Chemical abundances of Milky Way disk stars are empirical tracers of its enrichment history. However, they capture joint-information that is valuable to disentangle.

Modeling the Chemical Enrichment History of the Bulge Fossil Fragment Terzan 5

The Astrophysical Journal, 2023
Terzan 5 is a heavily obscured stellar system located in the inner Galaxy. It has been postulated to be a stellar relic, a bulge fossil fragment witnessing the complex history of the assembly of the Milky Way bulge.

PLATO as it is: A legacy mission for Galactic archaeology [PDF]

Astronomische Nachrichten, 2017
Deciphering the assembly history of the Milky Way is a formidable task, which becomes possible only if one can produce high‐resolution chrono‐chemo‐kinematical maps of the Galaxy. Data from large‐scale astrometric and spectroscopic surveys will soon provide us with a well‐defined view of the current chemo‐kinematical structure of the Milky Way, but it ...

Modelling the chemical evolution of the Milky Way [PDF]

, 2021
In this review I will discuss the comparison between model results and observational data for the Milky Way, the predictive power of such models as well as their limits. Such a comparison, known as Galactic archaeology, allows us to impose constraints on stellar nucleosynthesis and timescales of formation of the various Galactic components (halo, bulge,
