Massive first star binaries as new tools for Galactic archaeology [PDF]
EPJ Web of Conferences, 2022 Binary systems are important probes of the origin of stars with peculiar chemical features through the interactions between two stars. We have studied the evolution of a metal-free massive binary after the collision of the supernova ejecta with a low ...

Galactic Archaeology with TESS: Prospects for Testing the Star Formation History in the Solar Neighbourhood [PDF]
EPJ Web of Conferences, 2017 A period of quenching between the formation of the thick and thin disks of the Milky Way has been recently proposed to explain the observed age-[α/Fe] distribution of stars in the solar neighbourhood.

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.

Unveiling the Structure and Dynamics of Red Giants With Asteroseismology
Frontiers in Astronomy and Space Sciences, 2020 The Kepler mission observed many thousands of red giants. The long time series, some as long as the mission itself, have allowed us to study red giants with unprecedented detail. Given that red giants are intrinsically luminous, and hence can be observed

The SAGA so far: reading the history of the Galaxy with asteroseismology
EPJ Web of Conferences, 2015 Asteroseismology has the capability of delivering stellar properties which would otherwise be inaccessible, such as radii, masses and thus ages of stars.
