Notes. M∗ are derived using the evolutionary tracks of Baraffe et al. (1998). ∗ Object with strong veiling due to accretion. ∗∗ These stellar parameters are very uncertain and should be used with caution. See Appendix A for a discussion on this target. Subluminous YSOs. M⋆ reported with no uncertainties are for objects whose location on the HRD is at the edge of the tabulated evolutionary tracks.
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.
