12 and 18 μm Images of Dust Surrounding HD 32297

We present the first subarcsecond-resolution images at multiple mid-IR wavelengths of the thermally emitting dust around the A0 star HD 32297. Our observations with T-ReCS at Gemini South reveal a nearly edge-on resolved disk at both 11.7 and 18.3 mu m that extends similar to 150 AU in radius. The mid-IR is the third wavelength region in which this disk has been resolved, following coronagraphic observations by others of the source at optical and near-IR wavelengths. The global mid-IR colors and detailed consideration of the radial colortemperature distribution imply that the central part of the disk out to similar to 80 AU is relatively deficient in dust.
