A numerical model for the Serpens radio jet

The Serpens ("triple source") radio continuum jet shows a series of aligned knots with approximate to 1-2 " angular separations, forming a curved stru cture circumscribed within a cone of similar to 10 degrees full opening ang le. We present a high resolution, 3D numerical simulation of a jet with var iable ejection direction and velocity with parameters appropriate for the S erpens jet, from which we obtain predictions of 3.6 cm radio continuum maps . We find that the general morphology of the radio emission, and the time e volution of the successive knots, qualitatively agree with 3.6 cm VLA obser vations of the Serpens radio jet.
