Notes. The presence of ‘?’ indicates ambiguous classifications. For example, the star is classified as ‘SB1?’ when the detected RV difference between the two observed epochs mildly exceeds the 3σ uncertainty interval and no large asymmetries are detected in the line profiles. Superscripts ‘a’, ‘b’, ‘c’ refer respectively to the GSSP, TLUSTY, and CMFGEN models employed for the spectrum analysis of the sample stars.
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.
