Notes.UL = objects located well below the 30 Myr isochrone.
(m)
Stellar and accretion parameters not derived from UV excess. TD = transition disks. All stellar parameters have been derived using the Baraffe et al. (2015) evolutionary models except for objects with an asterisk, for which the models of Siess et al. (2000) were used.
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.
