... If BDs form from core 1 2 Testi et al. collapse, they should be associated to disks similar in properties to those found around low mass pre-main{sequence stars (TTauri stars; TTS). ...
... Unlike these objects, the colors of the ma jority of classical TTauri stars are more similar to those of heavily reddened mainsequence stars and can be ac counted for by standard disk models (e.g. Adams et al. ...

... The spectral energy distribution (SED) of TTauri stars at millimeter and submillimeter wavelengths has a shallow dependence on wavelength, consistent with opti- cally thin emission from millimeter-size grains (Beckwith & Sargent 1991). ...

... A problem in using this method to discriminate be tween young stars (members of the cluster) and field stars, is that some kind of young stars (the Weak Line TTauri stars or in general the infrared Class III sources) do not show infrared excess at all. ...

... The stellar volume densities estimated for the groups surrounding pre-main-sequence stars of intermediate mass show the transition from the low density aggregates of TTauri stars and the dense clusters around massive stars. ...
