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