Notes. The table gives results from the radiative transfer calculations with CMFGEN. The columns give the model name, the bolometric luminosity, the UVW1-band and V-band magnitudes and the Doppler velocity at maximum absorption measured in the Hα line profile, all given at one day after the onset of the collision. The model name in the first column consists of the masses of the two colliding stars, their relative velocity, and the impact parameter at collision. Numbers appearing within parentheses correspond to powers of ten.
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.
