Cumulative distribution functions of the RV separation (ΔVr) between the two stars in a binary system, ratio of temperatures (T1T2), ratio of radii (R1R2), and the relation between T1T2 and R1R2 in the fourth panel. The distribution of ΔVr is cut at the lower level of 15 km s−1 as explained in Sect. 6, while R1R2 starts at unity by construction because we define the primary as the star with a larger radius.

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.
