Notes. An asterisk marks models that are undergoing CHeB (i.e., post-main-sequence evolution). logṀ refers to our nominal (“higher”) mass-loss rate. The columns C, N, and O show surface mass fractions of carbon, nitrogen, and oxygen, respectively. We computed four synthetic spectra for each model in this table, corresponding to two different values of mass-loss rates (nominal and reduced) and clumping factors (D = 1 and 10).
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.
