Abstract

We have obtained continuum and emission line CCD images of the suspected HH object GGD 17. The object is associated with the T Tauri star Bretz 4. The images reveal a chain of HH knots. We believe that GGD 17 and the HH knots constitute a discontinuous optical jet excited by the star. Optical photometry and spectroscopy of Bretz 4 show that it is extremely active, with an emission line spectrum of class 5 and exhibiting strong photometric variability.
