HD 32297 is a young A-type star with a bright edge-on debris disk. The dust emission spectral energy distribution and scattered light spectrum are simultaneously modeled in terms of porous, cometary grains. The results imply that the debris disk of HD32297 may have an inner warm ring and an outer cold disk, which are seen in other young debris disks.
