Notes. Teff and log g come from a comparison of optical and HST/COS spectra with theoretical models. Mass and radius are derived from these using the Montreal evolutionary calculations and finite temperature mass-radius relations. The uncertainties (data in parentheses) are propagated and include possible systematic as well as statistical uncertainties. Distances are derived from the absolute flux in the ultraviolet (dHST) and from observed V (dV) and theoretical models. Uncertainties again include systematic and statistical contributions as far as possible. Below the horizontal line are the five comparison objects. *: Ancillary target, not used in sample statistics; 1: log g from Vennes et al. (2011a); 2: post-common envelope (close) binary; 3: spatially resolved (wide) binary; 4: exhibits excess infrared emission
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.
