A new Gaia census of OB associations within 1 kpc

Alexis L. Quintana, Nicholas J. Wright, Lilly A. Kormann +6

OB associations are primordial tracers of star formation and Galactic structure. Originally defined about 80 years ago, their historical membership lists have been superseded thank…

Quadrupole signature as a kinematic diagnostic to constrain bar properties : implications for the Milky Way

Soumavo Ghosh, Taavet Kalda, Paola Di Matteo +4

The presence of a 'butterfly' or a quadrupole structure in the stellar mean radial velocity () field of the Milky Way is well known from the Gaia and the APOGEE surveys. Pas…

The disc origin of the Milky Way bulge: On the high velocity dispersion of metal-rich stars at low latitude

Tristan Boin, Paola Di Matteo, Sergey Khoperskov +5

Previous studies of the chemo-kinematic properties of stars in the Galactic bulge have revealed a puzzling trend. Along the bulge minor axis, and close to the Galactic plane, metal…

New stellar age estimates using SPInS based on Gaia DR3 photometry and LAMOST DR8 abundances

L. Casamiquela, D. R. Reese, Y. Lebreton +8

Reliable stellar age estimates are fundamental for testing several problems in modern astrophysics, in particular since they set the time scales of Galactic dynamical and chemical…

Timing the Milky Way bar formation and the accompanying radial migration episode

Misha Haywood, Sergey Khoperskov, Valeria Cerqui +3

We derive the metallicity profile of the Milky Way low- disc population from 2 to 20 kpc from the Galactic centre in 1 Gyr age bins using the astroNN catalogue, and show that i…
