Notes. The first columns present the initial mass Mini in M⊙, the initial surface velocity νini in km.s−1, and the average surface velocity over the main sequence in km.s−1. For the H-, He-, and C-burning phases, the columns present the durations of the phase τphase in millions of years for H- and He- and in years for C-, the current total mass Mtot in M⊙, the surface velocity νsurf in km.s−1, and the surface mass fraction of helium Ysurf at the end of each nuclear burning phase.

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.
