The Milky Way in motion: gauging stellar trajectories that shape the Galactic thin disc
M. L. L. Dantas, R. Smiljanic, R. S. de Souza +2
As stars traverse the Milky Way, their orbits evolve through perturbations that alter their orbital radii. These changes arise from two mechanisms: churning, which modifies angular…
Stellar properties and chemical features of the Gaia Catalogue of Nearby Stars observed by GALAH DR4
P. H. R. de Andrade, M. L. L. Dantas, A. C. Soja
The Gaia Catalogue of Nearby Stars (GCNS) comprises approximately 330 000 stars within 100 pc of the Sun, as observed by Gaia data release 3 (Gaia DR3). Meanwhile, the GALAH DR4 su…
Connecting galaxies with their haloes -- from parsec to Mpc scales
K. Fahrion, J. van de Sande, K. R. Akhil +12
Galaxy evolution is driven by processes occurring across a wide range of scales, from star formation within giant molecular clouds (parsec scales) to outflows and secular evolution…
Playing CHESS with stars. I. Search for similar stars in large spectroscopic data sets
J. E. Martínez Fernández, S. Özdemir, R. Smiljanic +2
Context: Massive amounts of spectroscopic data obtained by stellar surveys are feeding an ongoing revolution in our knowledge of stellar and Galactic astrophysics. Analysing these…
Probing the origins. II. Unravelling lithium depletion and stellar motion: Intrinsic stellar properties drive depletion, not kinematics
M. L. L. Dantas, R. Smiljanic, D. Romano +4
In Paper I, we classified a stellar sample from the thin disc with a broad range in metallicity as being churned outward or inward, or blurred/undisturbed. In this paper (Paper II)…
Probing the origins. I. Generalised Additive Model inference of birth radii for Milky Way stars in the solar vicinity
M. L. L. Dantas, R. Smiljanic, R. S. de Souza +2
We employ a Generalised Additive Model (GAM) to address the limitations inherent in radial metallicity gradients predicted by chemical evolution models, thereby facilitating the es…
The interplay between super-metallicity, lithium depletion, and radial migration in nearby stars
M. L. L. Dantas, R. Smiljanic, R. Boesso +4
We report the discovery of a peculiar set of old super-metal-rich dwarf stars with orbits of low eccentricity that reach a maximum height from the Galactic plane between 0.5…
