Notes. The Gaia WD sample is expected to be roughly complete out to approximately 50 pc (Sect. 5). Here a limiting angular separation of 0.3′′ is assumed to differentiate between resolved and unresolved binaries. The table layout is the same as Table 4 with one extra column. The column on the far right shows the number of unresolved DWDs with periods less than ten days. The statistical error is omitted, as it is smaller than the systematic error, that is, variation between the different BPS models.
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.
