Playing CHESS with stars II. Homogeneous analysis of high-resolution optical spectra for a sample of 135 giants in 14 bulge globular clusters
S. Özdemir, R. Smiljanic, J. E. Martínez Fernández +3
Bulge globular clusters are key tracers of the complex formation history of the Galactic bulge, as they retain information on its past star-formation episodes. Their chemical abund…

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 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…
