INFRARED IMAGING OF HERBIG-HARO ENERGY-SOURCES

We present near-infrared (1-2.5 mu m) images of fields near the Herbig -Haro objects HH 24, HH 34, HH 43, HH 83, HH 89, HH 91, and HH 124, wh ich have been obtained in order to search for their energy sources and to determine the location of the latter relative to the Herbig-Haro o bjects themselves, to measure their near-infrared colors, and to study their immediate environments. We provide J, H, and K photometry of th e sources, and discuss their near-infrared energy distribution with th e aid of a (J - H) vs. (H - K) diagram. Energy sources for all but HH 91 were detected and studied. Those of HH 89 and of HH 124 are new det ections, the source HH 83 IRS is found to be better aligned with the H H 83 jet than previously thought, and HH 34 IRS has brightened by abou t 0.5 mag in all filters. In HH 91 the bright knot where the energy so urce was expected was found to have colors typical of pure H-2 emissio n. All of the energy sources are intimately associated with nebulosity .
