Notes. Column 1: name of the disks observed with PdBI. Columns 2 and 3: right ascension and declination of the targets. Column 4: spectral type. Column 5: effective temperature of the central star. Column 6: estimated distance to the target. Columns 7–9: stellar luminosity, radius and mass respectively. Column 10: accretion rate. Column 11: radial cavity extension (R and S implies that the cavity is either resolved or derived from SED modelling, respectively). Column 12: flux at 345 GHz. The data is from Andrews et al. (2011a) for LkHα 330 and UX Tau A, and from Espaillat et al. (2012) for LRLL 31 and LRLL 67 and references therein. Column 13: flux at 100 GHz from the PdBI observations. Column 14: calculated flux at 300 GHz (~1 mm) and the error assuming an additional systematic uncertainty from calibration of 15%. Column 15: integrated spectral index calculated with the observed fluxes (Cols. 13 and 14).

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.
