The chemical enrichment histories across the Milky Way disk
Valeria Cerqui, Misha Haywood, Owain Snaith +2
The variation of metal production over time and its dilution in the interstellar medium depend on the star formation and gas accretion rates. Measuring age-chemistry relations acro…

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…
