Fig. 2


Elemental abundances of 16 Cyg A (upper panel) and B (lower panel) based on our manually measured solar abundances as a function of condensation temperature for light elements (Z ≤ 30). Solid lines represent the linear fits with a slope of 3.99 ± 0.58 × 10−5 for the A component and 2.78 ± 0.57 × 10−5 for 16 Cyg B. Red triangles correspond to the molecule-based abundances of C, N, and O.

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.
