Abstract:
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, B335, and PV Cephei that are probably associated with the powering sources of these bipolar outflows. For objects with low bolometric luminosity (L(bol) less-than-or-equal-to 100 L.), we find a marginal correlation between the momentum rate in the molecular outflow and the centimeter continuum luminosity, P is-proportional-to S(v) d2. 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.
