Galactic archaeology meets exoplanets: linking stellar birth radii to exoplanet demographics
M. L. L. Dantas, J. J. García-Delgado, I. Rebollido +1
Stars observed in the solar vicinity were not necessarily born there. Radial mixing can redistribute stellar populations across the Galactic disc, decoupling their present-day loca…
The T-GEX project. II. Chrono-chemo-dynamic signatures of UV-bright FGK stars
D. Beltrán, M. L. L. Dantas, R. Smiljanic +1
We compare the ages, chemical abundances, Galactic orbits, and inferred birth environments of 37 T-GEX stars with strong (G1), normal (G2), and intermediate (G3) UV emission. The g…
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
We constructed the Tiny Gaia-ESO + GALEX (T-GEX) catalogue by combining Gaia-ESO spectroscopy, Gaia DR3 astrometry, GALEX UV photometry, and 2MASS and AllWISE infrared measurements…
Probing the origins. III. Exoplanet demographics across Galactic birth radii
Juan José García-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…
