The Geneva-Copenhagen suvery of the solar neighbourhood ll:New uvby calibrations and rediscussion of stellar ages, the G-dwarf problem, age-metallicity diagram, and disk heating mechanisms of the disk

Key Points

• The analysis addresses the g-dwarf problem through refined uvby calibrations, aiding in age determinations.
• Results indicate an updated age-metallicity diagram that supports ongoing discussions in stellar evolution.
• Observational analysis utilizing Geneva-Copenhagen survey data enhances our understanding of disk heating mechanisms.
• These findings highlight the complexity of stellar ages and metal content affecting galactic structure.
