| Abstract: |
We present 11.7μm observations of nine late-type dwarfs obtained at the Keck I telescope. Our targets were selected for their youth or apparent IRAS 12μm excess. For all sources, excess infrared emission is not detected. We find that stellar wind drag can dominate the circumstellar grain removal and plausibly explain the dearth of M Dwarf systems with infrared excesses. |
