Curiel, S. ; Rodriguez, L. F. ; Moran, J. M. ; Canto, J. Abstract Results are presented of a multifrequency, multiconfiguration study of the continuum emission from the triple radio continuum source in Serpens, observed with Very Large Array of the NRAO, which was carried out to investigate the spectral indices of the multiple components in Serpens in detail, to study the morphological characteristics of this radio source, and to resolve the angular structure of its components. In addition, the position of the H2O maser, known to be near this radio source was measured using the same instrument. On the basis of these observations, the triple radio continuum source in Serpens is identified as a young radio jet, with a dynamical age of only about 60 years, emanating from the central component. This radio jet exhibits a one-sided morphology that is very similar to that observed in optical Herbig-Haro jets, suggesting that jets associated with young stellar objects are intrinsically unipolar within the dynamical ages of the main jets. It is proposed that the Serpens radio jet could be a proto-Herbig-Haro system in an early stage of evolution.
