| Abstract: |
We report recent observations with the Spitzer Space Telescope of the Wolf-Rayet stars WR102ka and WR102c, located in the vicinity of the Galactic Center. We used the short-high module of the IRS to obtain high quality mid-IR spectra. In this range from 10 – 20μm, the spectra of both stars are dominated by dust emission, partly of circumstellar origin. Dust has not been detected before around WN types stars. |
