Scientific paper

We report a sensitive VLA search for 3.6 cm continuum emission from the central regions of eight outflows. We detected continuum sources in RNO 43, Haro 4-255 FIR, B355, and PV Cephei that are probably associated with the powering sources of these bipolar outflows. For objects with low bolometric luminosity, we find a marginal correlation between the momentum rate in the molecular outflow and the centimeter continuum luminosity. This correlation is in agreement with models that explain the radio continuum emission as arising in shock-ionized gas in the surroundings of the powering source of the molecular outflow. We also detected radio continuum emission from the Herbig-Haro object 32A.
