Notes. Each column has the following meaning. Tc: central temperature at the end of the calculation, τH: duration for core hydrogen burning, τf: evolutionary time from the beginning to the end of the calculation, Mf: final mass, MHe − Core: size of the helium core at the end of the calculation (the upper boundary is defined as the location where the hydrogen mass fraction becomes less than 0.01), MCO − Core: size of the carbon-oxygen core at the end of the calculation (the upper boundary is defined as the location where the helium mass fraction becomes less than 0.01), Ys,TAMS: surface helium mass fraction at the terminal age of the main sequence, Ys,f: surface helium mass fraction at the end of the calculation, Xs,C: surface carbon mass fraction at the end of the calculation, Xs,N: surface nitrogen mass fraction at the end of the calculation, Xs,O: surface oxygen mass fraction at the end of the calculation, Jf: total angular momentum at the end of the calculation, j3M,f: mean specific angular momentum of the innermost 3   M⊙ at the end of the calculation, jCO,f: mean specific angular momentum of the carbon-oxygen core at the end of the calculation. The different modes of evolution are indicated by NE (normal evolution), TE (transitionary evolution) and CHE (chemically homogeneous evolution), as defined in Sect. 3.

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.
