Notes. Columns are source ID, spectral type, temperature at an optical depth of two-thirds and 20, radius at an optical depth of two-thirds and 20, colour excess, luminosity, mass-loss rate, terminal velocity, maximum clumping factor, hydrogen mass fraction, helium mass fraction, carbon mass fraction and nitrogen mass fraction.
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.
