Scientific paper

An infrared image of HH 43 in the 1-0 S(1) emission line of molecular hydrogen has been obtained at high spatial resolution (0arcsec.6 pixel-1). Comparison of this image with optical CCD images obtained at comparable resolution in the emission lines of Hα and [S II] reveals a very strong spatial correlation between the infrared and optical emission. It is suggested that dissociative J-shocks, in which H2 can reform in the postshock gas, are present in HH 43.
