RAGA, A. C. et al. An Intepretive Ballistic Model for Quasi-Symmetric Bipolar Jet Systems. Rev. mex. astron. astrofis [online]. 2011, vol.47, n.2, pp.289-295. ISSN 0185-1101.

We present an analytic, ballistic model for quasi-symmetric jet/counterjet systems, considering both the non-relativistic and the relativistic cases. The model considers the presence of ejection time and velocity asymmetries, which produce offsets between the positions of the knots in jet/counterjet pairs. A fit of the non-relativistic model predictions to observations of two quasi-symmetric HH outflows (HH 34 and HH 111) allows us to obtain the magnitudes of the ejection time and velocity asymmetries of these systems.
