| Abstract: | Near Infrared spectroscopic observations (1.2–2.4µm) of two condensations (HH 1A & HH 1G) of Herbig-Haro object 1 are used to explore the nature of its molecular shocks and extinction. The H2 emission lines display a more complex behaviour than that accounted for C or J type shock models. The extinction, determined from the ratio of Fe II] 1.257 & 1.644µm, is higher than what is expected from optical S II] measurements, and it may indicate real discrepancies between the optical and IR regions of the ISM extinction curve. |
