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 Originally defined about 80 years ago, their historical membership lists have been superseded thank…
Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake: Resolved Stellar Populations Studies in M31 and its Satellites
C. Gallart, E. Fernández-Alvar, A. B. A. Queiroz +48
A 30 m class optical/near-IR telescope in the Northern Hemisphere, equipped for diffraction-limited imaging and high-resolution, multi-object spectroscopy of faint stars, would ena…
Gaia FGK Benchmark Stars: spectral library, metallicities and abundances of and Fe-peak elements of the third version
L. Casamiquela, C. Soubiran, P. Jofré +14
The accurate determination of chemical abundances in stars plays a pivotal role in understanding stellar structure and evolution, nucleosynthesis, and the chemical enrichment histo…
Open clusters in the outer disc studied with MEGARA@GTC Auner 1 and Berkeley 102
J. Carbajo-Hijarrubia, R. Carrera, F. Anders +4
Open clusters offer crucial insights into stellar nucleosynthesis and the chemical evolution of the Galactic disc, as their ages and distances can be determined with higher accurac…
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…
