Abstract

With a combination of submm and mm bolometer arrays, we have observed a sample of 24 low mass stars and brown dwarfs, spanning the M2-M9 spectral types in the Taurus star-forming region. This study extends mass range coverage of previous larger scale surveys of pre-Main Sequence stars in Taurus. Of the 12 targets observed with SHARCII at 350um and the 12 targets observed with MAMBO at 1.2mm, 9 are detected for the first time at these wavelengths. The fluxes range from 2.8mJy at 1.2mm for the brown dwarf CFHT Tau 6 to 2.6Jy at 350um for the low mass star IRAS04158. In conjunction with previously reported fluxes at other wavelengths, we have modeled the SEDs of these system with the radiative transfer code MCFOST to estimate disk properties such as disk mass and dust properties.
