Abstract :
We will present first results from 7-mm continuum observations of a sample of T Tauri stars obtained
at the very large array. Since most of the circumstellar disks could be spatially resolved, their mm spectral
energy distributions can readily yield information on the characteristic dust grain size within the disks. Our
sample of 14 young low-mass stars in the Taurus star-forming region is the largest coherent set of pre-main-
sequence stars yet investigated for unambiguous evidence of dust particle growth. Grains significantly larger than
submicron-sized ISM dust seem to be ubiquitous. Our findings indicate that grain growth to mm and even cm-sized
dust particles is a rapid process.
