Scientific paper

We wish to obtain high signal-to-noise, moderate dispersion time- series spectroscopy of the dust-producting Wolf-Rayet star WR 137. These data will be used to examine the frequency, life-times, and velocity distributions of density inhomogeneities within the wind, and to search for periodic modulation of the line-profile morphology indicative of large-scale azimuthal structure. Evidence for rotational modulation will provide strong support for the hypothesis that WR 137 has an equatorially-compressed wind as a result of rapid rotation, and that it is a carbon-sequence analogue of WRs 6 and 134.
