Notes. Numerical estimates from Sect. 4.2. Columns 1–8 indicate names, spectral subtypes, and empirical stellar parameters for putatively single WC/WO stars in analogy to Table 1. The two bottom rows indicate wind models for WC stars from Gräfener & Hamann (2005). Columns 9–16 indicate wind parameters that are numerically determined, as outlined in Sect. 4.2. Pr and Pg denote the radiation and gas pressure at the sonic point obtained from this method.

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.
