Notes. vj,0 is the jet velocity in km s−1; A is the amplitude of variation in the jet velocity; na and nj are the ambient medium and jet (numerical particle) density; η = nj∕na is the jet to ambient medium density ratio; Ta and Tj are the ambient medium and jet temperatures (in K); τP is the precession period, Ntot the number of different jet injection period, and τe is the jet velocity variability period.
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.
