Notes. (a)The mean [Fe/H] of individual measured values for stars of each cluster in Dal Ponte et al. (2025). (b)Ages are taken from Cantat-Gaudin et al. (2020). (c)This association is inferred to be a part of NGC 752, as a tidal tail (Dal Ponte et al. 2025), but we treat it as a separate entity in this study. (d)For the Theia 1214 stars, the age and mass were derived in this study.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
