Notes. As usual, A(X)=12 + log(N(X)/N(H)), [X/H]=A(X)* − A(X)⊙ and [X/Fe]=[X/H]−[Fe/H]. The six N-rich stars are at the top of the table, followed by the two stars (HD 97916 and HD 166913) that were found to have a normal N abundance. The adopted solar abundances are in bold. (*) Oxygen abundance following Ramírez et al. (2012).
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.
