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…
