Notes. Measurements were done for TOI-1430 (for all elements but Fe I, Fe II, Ti I and Ti II which refer to TOI-5082) and TOI-5398 (for all elements but Fe I, Fe II, Ti I and Ti II which refer to TOI-1136), respectively the coolest and the warmest stars in our sample. The values in table refer to the differences between the abundances obtained with (− and +) and without the uncertainties in stellar 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.
