Notes. The 1σ errors are given. Rpole is the radius toward the pole, Rpoint is the radius measured toward the other component, Rside is the radius measured toward the side, Rback toward the Lagrangian point L2 and Rmean is the geometrical mean between Rpole, Rside, and Rback. The bolometric albedos (coefficients of reprocessing of the emission of a companion by “reflection”) and the gravity darkening coefficients are both set to 1.0 for the different components. The ratio, lp/ls, indicates the luminosity of the primary to the secondary.
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.
