Two remarkable Herbig-Haro objects in the NGC 2264 region

Two groups of Herbig-Haro objects, designated HH 124 and HH 125, have been discovered in the NGC 2264 complex. Direct plates, narrow-band CCD images, low-dispersion spectra and high-resolution line profiles of the sources have been obtained. HH 124, which lies to the north of NGC 2 264, has a typical linear structure with HH knots on both sides of an IRAS source which is situated close to a central emission knot. The knots of HH 124 show spectra typical of low-velocity shocks and the knots on opposite sides of the central one show blue- or redshifted emission, characteristic of a bipolar outflow tilted to the line of sight
