Observational identification of a low-α Splash population in APOGEE DR17 and GASTRO simulations showing that clumpy proto-disk scattering, but not a major merger alone, heats old thin-disk stars to form both high- and low-α Splash components.
A neural network trained on simulations infers stripping times for Sagittarius stream stars from phase-space data, measuring a 0.3 dex/Gyr metallicity gradient and estimating ages for globular clusters such as Pal 12 and NGC 2419.
A single end-to-end Transformer model unifies stellar labels from heterogeneous spectroscopic surveys into a self-consistent scale without post-hoc recalibration.
Reprojects abundances of 199k stars into 4 patterns, identifying enrichment pathways with strong chemo-spatial, age, and vertical correlations plus a transition at ~6 Gyr.
Revised radial-velocity response model including V_R,sin and V_R,cos applied to Milky Way kinematic data constrains spiral pitch angle to ~10°, density contrast 5-18%, and pattern speed 10-20 km/s/kpc.
Gaia-HELIX is a new catalogue of 28,394 bona-fide Hα emitters identified in Gaia DR3 XP spectra, after removing 95% of initial candidates that were M-type star mimics.
Three accelerating stars yield one stellar companion at 166 AU, one 45 Jupiter-mass object at ~18 AU, and one 9.5 Jupiter-mass object at 6.4 AU that is 65% likely to be a planet.

Gaia Exoplanet Orbits, Demographics, and Evolution Survey (GEODES): Characteristics of Three Long-Period Companions Accelerating their Host Stars
Three accelerating stars yield one stellar companion at 166 AU, one 45 Jupiter-mass object at ~18 AU, and one 9.5 Jupiter-mass object at 6.4 AU that is 65% likely to be a planet.
