Notes. Values for the 2003 data are taken from Schmitt & Robrade (2007). Values in brackets pertain to the 2003 observation with strongly enhanced X-ray emission. This observation stands out from the rest of the observations and might not be representative of the X-ray emission of AA Tau.
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.
