Abstract
Full Iso-Lws spectral scans between about 45 to 190 µm of 17 individual HH objects in 7 star forming regions have revealed essentially only [O i] 63 µm line emission, implying that the Fir cooling of these objects is totally dominated by this line alone. In this case, J-shock models can be used to determine the mass loss rates of the HH exciting sources. These mass loss rates are in reasonably good agreement with those estimated for the accompanying CO flows, providing first observational evidence that HH and molecular flows are driven by the same agent. The L mech — L bol relation, based on our results with the Lws, implies that young stellar objects of lower mass are loosing mass at relatively higher rates than their more massive counterparts.
