Using results and calibrations from a previous paper (Gullbring et al. 1997), we estimate disk accretion rates for preÈmain-sequence stars in the Taurus and Chamaeleon I molecular cloud complexes. The median accretion rate for T Tauri stars of age D1 Myr is D10~8 yr~1 ; the intrinsic scatter at a M _ given age may be as large as 1 order of magnitude. There is a clear decline of mass accretion rates M0 with increasing age t among T Tauri stars. Representing this decline as we estimate M0 P t~g… CONTINUE READING
