Notes. This table will be available in its entirety in machine-readable form at the CDS. We provide for each star the Gaia-DR2 identifier and position, J-band photometry and extinction in this band, spectral type, effective temperature, bolometric luminosity derived in this study, ages estimates inferred from the Baraffe et al. (2015, BHAC15) and Siess et al. (2000, SDF00) models, and the subgroup to which the star belongs. We used the spectral types and extinctions compiled by Esplin et al. (2017) and Spezzi et al. (2008) for Cha I and Cha II stars, respectively.
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.
