Raga, A. C. ; Bohm, K. -H. Abstract The position-dependent emission-line profiles (called 'position-velocity diagrams' by Choe, Bohm, and Solf) for the lines H-beta, the forbidden line of N II at 6583 A, the forbidden line of S II at 6731 A, the forbidden line of O I at 6300 A, and the forbidden line of O III at 5007 which are formed in a (somewhat simplified) model of a radiating interstellar bow shock of high Mach number have been computed. Such models have been suggested as an explanation of the emission-line spectra of Herbig-Haro objects in connection with the 'interstellar bullet model'. Some of the restrictive assumptions used in related earlier work have been eliminated. Comparing the present results to the recent high-resolution long-slit coude spectra of Herbig-Haro objects (obtained by Bohm and Solf), some important similarities are discussed.
