Proper Motions of the Jets in the Region of HH 30 and HL / XZ Tau . Evidence for a Binary Exciting Source of the HH 30 Jet

Abstract

We present [SII] images of the HH 30 and HL/XZ Tau region obtained at two epochs, as well as long-slit optical spectroscopy of the HH 30 jet. We measured proper motions of ∼100–300 km s for the HH 30 jet and counterjet, and of ∼120 km s for the HL Tau jet. Inclination angles with respect to the plane of the sky are 0–40 for the HH 30 jet and 60 for the HL… (More)
