Scientific paper

The authors have combined IUE and optical spectral data on a supernova remnant in M33 in order to determine the abundance of carbon in the interstellar gas of M33. They have used new shock model calculations to guide the interpretation and find that a substantially lower value of the ratio C/O than has been assumed previously for M33 may be necessary to explain the data. However, some inconsistencies in the observed and predicted line intensities indicate that the spectra may be partly contaminated by H II region emission or that the preshock gas has been ionized by nearby stars.
