The T-GEX project. I. Stealth UV-bright Sun-like stars in the Galaxy as candidate contributors to the UV upturn
M. L. L. Dantas, D. Beltrán, R. E. Giribaldi +3
The authors created a catalog of 37 Sun-like stars by combining Gaia-ESO spectroscopy, Gaia DR3 astrometry, GALEX UV photometry, and infrared data, and identified UV‑bright sub‑pop…
Probing the origins. III. Exoplanet demographics across Galactic birth radii
Juan José GarcÃa-Delgado, M. L. L. Dantas, Isabel Rebollido +1
We quantify radial mixing in exoplanet hosts and explore links between birth environment, orbital evolution, planetary architecture, and Galactic habitability. We constructed a hom…
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. MartÃnez Fernández, S. Ãzdemir, 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…
