Transitional disks are protoplanetary disks with opacity gaps/cavities in their dust distribution , a feature that may be linked to planet formation .
We perform Bayesian modeling of the three transitional disks SZ Cha , CS Cha and T25 including photometry from the Herschel Space Observatory to quantify the improvements added by these new data .
We find disk dust masses between 2 \times 10 ^ { -5 } and 4 \times 10 ^ { -4 } M _ { \odot } and gap radii in the range of 7-18 AU , with uncertainties of \sim one order of magnitude and \sim 4 AU , respectively .
Our results show that adding Herschel data can significantly improve these estimates with respect to mid-infrared data alone , which have roughly twice as large uncertainties on both disk mass and gap radius .
We also find weak evidence for different density profiles with respect to full disks .
These results open exciting new possibilities to study the distribution of disk masses for large samples of disks .
