(A) NICMOS image of the r ⩽ 33 region of the HD 32297 disk (replicated from Schneider et al. 2005; the gray circle overlays the r = 03 coronagraphic obscuration) separately fitting image isophotes on opposite sides of the star (yellow dotted lines) indicates a departure from a linear fit to both sides of the disk (green line). (B) NICMOS image astrometrically inset with the surrounding large-scale asymmetric nebulosity seen with wider-field, ground-based imaging (r ⩾ 5'', reproduced from Kalas et al. 2005) suggested a then unseen contiguous debris structure undergoing possibly extrinsic perturbations. In both panels, residual diffraction spikes in the NICMOS image, not co-incident with the edge-on disk, have been digitally masked.
