Scientific paper

We present FUSE data on OVI absorption lines observed toward 8 stars behind the Vela supernova remnant (SNR). We compare the OVI observations with IUE observations of CIV absorption toward the same stars. The column density ratios and magnitudes are compared to both steady shock models and results of hydrodynamical SNR modeling. We find that the models require the shock to be relatively slow ( ~100-170 km/s) to match the data. We discuss the implications of our results for models of the evolution of the Vela SNR. This research was supported by NASA grant NAG5-9002.
