Strong Toroidal Recirculation Zones at the Inner Dust Rim as the Origin of Meteoric Chondrules and Calcium-Aluminum Inclusions
Peter Todd Williams
We hypothesize strong (transonic) twin toroidal recirculation zones above and below the accretion disk midplane, rather close-in to the protosun, to be the source of chondrules and…

The Salinas Reactive-Flow Rate Model
Peter Todd Williams
We present the model Salinas and discuss its results in modeling corner-turning behavior, including failure and the formation of dead zones. Salinas is a recent reactive-flow model…

Can Hyperbolic Diffusion Help Explain Sharp Edges in the Gaps in Saturn's Rings?
Peter Todd Williams
We explore whether hyperbolic diffusion may help explain sharp edges in the gaps in Saturn's rings. Sharp edges are conventionally understood to be due to angular momentum flux rev…
