Notes.Given are the solar-normalised abundance ratios with respect
to Fe (relative to hydrogen for iron and lithium). We use the usual notation:
[A/B] =
[log ϵ(A)− log ϵ(B)] − [log ϵ(A)− log ϵ(B)] ⊙
where log ϵ(A) = 12 + A
H)]
(
is the number density of the species). Our final values for the CoRoT targets are
provided in the last column. The number in brackets gives the number of lines used
for a given ion.
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.
