Exploring the Milky Way stellar disk

open access: yesAstronomy & Astrophysics
Context. Elemental abundances in long-lived dwarf stars provide important constraints on the chemical evolution of the Galactic disk. While several large spectroscopic surveys provide abundances for vast stellar samples, small homogeneous samples remain ...

StarFlow: Leveraging Normalizing Flows for Stellar Age Estimation in SDSS-V DR19

open access: yesThe Astronomical Journal
Understanding the ages of stars is crucial for unraveling the formation history and evolution of our Galaxy. Traditional methods for estimating stellar ages from spectroscopic data often struggle with providing appropriate uncertainty estimations and are

TransformerPayne: Enhancing Spectral Emulation Accuracy and Data Efficiency by Capturing Long-range Correlations

open access: yesThe Astrophysical Journal
Stellar spectra emulators often rely on large grids and tend to reach a plateau in emulation accuracy, leading to significant systematic errors when inferring stellar properties.

The dynamical memory of tidal stellar streams

open access: yesAstronomy & Astrophysics
Context. Stellar streams offer one of the most sensitive probes of the Milky Way’s gravitational potential, as their phase-space morphology encodes both the tidal field of the host galaxy and the internal structure of their progenitors.

Galactic Archaeology with TESS: Prospects for Testing the Star Formation History in the Solar Neighbourhood

open access: yesEPJ 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.
