Notes. Amongst the first-nearest-neighbor couples of stars (A, B), the ultra wide Pairs (UWPs) are defined as mutual first nearest neighbors. Column 1: couple reference (this work). Columns 2–5 (Star A): the star reference (this work, see Table C.1), presence of a spectroscopic binary associated to the star/stellar system A (“S” means one spectroscopic binary, “SS” means two spectroscopic binaries), the common Name of the star A, n∗ A the total number of stars, above the unity if the star is not single (spectroscopic binaries are counted as one component), the class of the (primary star). Columns 6–9 (Star B): the star reference (this work, see Table C.1), presence of a spectroscopic binary associated to the star/stellar system A (“S” means one spectroscopic binary, “SS” means two spectroscopic binaries), the common Name of the star B, n∗ B: the total number of stars, above the unity if the star is not single (spectroscopic binaries are counted as one component), the class of the (primary star). Columns 10–11: the separation of the two stellar components A and B and their total number of stars as a (hierarchical) couple. Column 12: flag to indicate whether the each star A and B has been observed at high angular resolution (**), if only one component has been observed at HAR (*) or if none of them have been observed at HAR (no mark). Column 13: “C” indicates a ultra wide pair candidate since the couple are mutual nearest neighbours. The presence of an [Y], this couple has been confirmed as gravitationally bound binaries using astrometric and spectroscopic techniques as reported in the work of Kraus & Hillenbrand (2009b) who focused on binaries with separation less than 4200 AU. The delimitation of separation range in their study is marked by a single horizontal line in the table.

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.
