Notes. Disk type from Barenfeld et al. (2016), Luhman & Mamajek (2012), Carpenter et al. (2006). Stellar properties obtained using the Baraffe et al. (2015) evolutionary models, apart from the target 2MASSJ15583692-2257153, for which Siess et al. (2000) models were used since the stellar mass was higher than the maximum one modeled by Baraffe et al. (2015). Disk masses are updated from Barenfeld et al. (2016) using the distance inferred from the Gaia DR2 (Gaia Collaboration 2018) parallaxes. When no uncertainties on the distance is reported, the mean distance to the targets of 145 pc was adopted. Possible non-accretors are reported with “N” in the Acc? column. The values reported here for the accretion rate of non-accretors are considered in this work as upper limits.
