| Abstract: |
We report on a mid-infrared survey of Wolf-Rayet stars using the Spitzer IRS/SH instrument for types WN4-WN7 and WC4-WC7. Strong emission line spectra are seen, including forbidden emission lines. Surprisingly, the WN stars appear to show broad emission “bumps” that may be consistent with silicate dust grains. |
