Notes. The adopted solar reference abundances are from Magg et al. 2022. The quoted errors are the standard deviations divided by the square root of the number of lines used (which is reported in brackets), with the exception of a conservative assumption of 0.1 dex when only one line was measurable (in the case of the following species: S, K, Cu, Zn and Ce). The global error of each abundance ratio amounts to 0.10-0.15 dex, due to the uncertainties in the atmospheric parameters.
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.
