Abstract Comet C/1995 O1 (Hale–Bopp) has provided an unprecedented opportunity to observe a bright comet over a wide range of heliocentric distances. We present here Spitzer Space Telescope observations of Hale–Bopp from 2005 to 2008 that show a distinct coma and tail, the presence of which is uncommon given its large heliocentric distance (21.6 AU and 27.2 AU, respectively). The morphology of the dust is compared to dynamical models to understand the activity of the comet. Our analysis shows… Expand

Fine-scale structure in cometary dust tails I: Analysis of striae in Comet C/2006 P1 (McNaught) through temporal mapping
Abstract Striated features, or striae, form in cometary dust tails due to an as-yet unconstrained process or processes. For the first time we directly display the formation of striae, at C/2006 P1Expand

Finite Lifetime Fragment Model 3 for striae formation in the dust tails of comets (FLM 3)
Abstract The striations in the Type II tail of the comets are called striae. The origin of the striae has been poorly understood. We present a new dynamical model to explain the structure of theExpand
