Fig. 2


Contrast of the stellar density distribution. (upper left) model A: σR = 0.1, ϵ = 0.1 (upper right) model B: σR = 0.2, ϵ = 0.1 (lower left) model C: σR = 0.1, ϵ = 0.3 (lower right)model D: σR = 0.2, ϵ = 0.3. The major bar axis orientated at 34 degrees from the horizontal axis. Corotation at R = 0.52 and OLR at R = 1. Range of colours is given with an arbitrary scale, different for each image to maximise the contrast (red is positive and blue negative).

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.
