VLA DETECTION OF THE EXCITING SOURCES OF HH-34, HH-114, AND HH-199

We present sensitive VLA observations at 3.6-cm of four Herbig-Haro fi elds: HH 34, HH 114, HH 199, and RH 212. In all fields but the last we detect radio sources that are probably associated with the exciting s ource of the region. In the case of HH 34, our detection of a radio co unterpart supports the notion that newborn stars which are actively pr oducing RH flows generally emit in the cm radio continuum at levels th at are detectable with a moderately long (a few hours) integration mad e with the VLA. In the HH 114 field, we detect independent sources ass ociated with both an IRAS source and a millimeter object in the region . Our present observations cannot favor either of the sources as the d ominant exciting object in the region. Finally, in HH 199 we detect a source that could be a thermal jet or an unresolved radio binary and t hat is associated with the IRAS source in the field.
