Scientific paper

The authors present observations of the 63 μm [O I] line from Herbig-Haro objects and their exciting stars. They detected [O I] emission toward the HH-exciting stars T Tau, DG Tau, L1551 IRS 5, and toward the HH objects HH 7-11, HH 42A, and HH 43 which are displaced from their exciting stars. The [O I] emission is associated with these flows on the basis of its spatial coincidence and its negative radial velocities. The observed [O I] lines at 6300 Å and 63 μm, and the S(1) 1-0 H2 emission, in HH 7-11, HH 42A, and HH 43 can be matched by simple combinations of J and C shocks. The [O I] 63 μm luminosity is a measure of the mass loss from the objects and the authors derive mass-loss rates for the exciting stars of order 10-7 to 10-6M_sun;yr-1.
