Scientific paper

We have obtained narrow-band images of the Herbig-Haro object HH 29 in a number of important shock diagnostic emission lines under excellent seeing conditions. Some 25% of the total line flux originates from a resolved compact source which makes up only 4% of the projected emitting area of HH 29. This feature shows a marked elongation in the same direction as the molecular outflow emanating from the young stellar object L t55 1-IRS 5. The essentially extinction-free [O III]/Hβ ratio delineates the spatial distribution of the gas heated by strong shocks. For these regions the extinction map, derived from Hα and Hβ observations, shows a patchy dust distribution on scales of a few hundred AU and with column density contrasts of about 2-6. The distribution of the [O I], [O II] and [O III] emission indicates pre-shock densities ≥ 300 cm-3 and bow shock velocities of about 90 km s-1. The cooling zone appears spatially resolved in the principal direction of the shock flow.
