Notes. Densities and temperature are derived form the best fit model for each object. The observed mass-loss rates derived at the ionisation front are from Henney & O’Dell (1999) for HST10 and 244-440, and derived by us from Hα images for 105-600 (see text for details). A central star of 1 M is used in the calculation of the mass-loss rate for 105-600 while, for the Orion proplyds, we used a 0.1 and 1 M for the supercritical and subcritical cases respectively.

Disk radius roughly approximated by this study (see Sect. 4.1.2).

(b)

Disk radius estimated by spatially resolved observation: HST10 from Chen et al. (1998), 244-440 and 203-506 from Vicente & Alves (2005).
