Notes. The third-to-last row shows the percentage of merging binaries with a GW coalescence timescale (tGW) of the final binary of less than a Hubble time (tHubble ≡ 1.4 × 1010 yr). The second-to-last and the last rows show the percentage of highly eccentric mergers (e > 0.1) at fGW = 10 Hz in proportion to the total number of interactions and in-cluster mergers, respectively. The first two rows indicate the initial mean relative velocity between the binary–single and binary fraction, respectively.
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.
