We derive a new metallicity distribution of G dwarfs in the solar neighbourhood, using uvby photometry and up-to-date parallaxes. Our distribution comprises 287 G dwarfs within 25 pc from the Sun, and differs considerably from the classic solar neighbourhood distribution of Pagel & Patchett and Pagel by having a prominent single peak around [Fe/H] = −0.20 dex. The raw data are corrected for observational errors and cosmic scatter assuming a deviation σ = 0.1. In order to obtain the true… CONTINUE READING
