We present Keck images of the dust disk around β Pictoris at λ = 17.9 μm that reveal new structure in its morphology. Within 1'' (19 AU) of the star, the long axis of the dust emission is rotated by more than 10° with respect to that of the overall disk. This angular offset is more pronounced than the warp detected at 35 by the Hubble Space Telescope (HST) and is in the opposite direction. By contrast, the long axis of the emission contours ~15 from the star is aligned with the HST warp… Expand
Mid-infrared images of β Pictoris and the possible role of planetesimal collisions in the central disk
Thermal infrared images of the central disk imply that the brightness asymmetry results from the presence of a bright clump composed of particles that may differ in size from dust elsewhere in the disk, which is suggested to result from the collisional grinding of resonantly trapped planetesimals or the cataclysmic break-up of a planetesimal.
