Abundances for two cases (red and orange lines) that can both reproduce the bolometric luminosity evolution. While both produce r-process material, one case produces the third r-process peak (Ye = 0.2 and v = 0.1c), but the other (Ye = 0.3 and v = 0.2c) does not. Thus, from the bolometric lightcurve alone the absence/presence of lanthanides cannot be inferred. For comparison, we also show a case (green line) with large Ye = 0.4 (v = 0.2c) that only produces elements with A < 90. That case does not fit the bolometric luminosity.

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.
