Saturn Forms by Core Accretion in 3.4 Myr
Sarah E. Dodson-Robinson, Peter Bodenheimer, Gregory Laughlin +3
We present two new in situ core accretion simulations of Saturn with planet formation timescales of 3.37 Myr (model S0) and 3.48 Myr (model S1), consistent with observed protostell…
Ice Lines, Planetesimal Composition and Solid Surface Density in the Solar Nebula
Sarah E. Dodson-Robinson, Karen Willacy, Peter Bodenheimer +2
To date, there is no core accretion simulation that can successfully account for the formation of Uranus or Neptune within the observed 2-3 Myr lifetimes of protoplanetary disks. S…
Turbulence driven diffusion in protoplanetary disks - chemical effects in the outer disk
K. Willacy, W. D. Langer, M. Allen +1
The dynamics and chemistry of protostellar disks are likely to be intricately linked, with dynamical processes altering the chemical composition, and chemistry, in turn, controllin…
Turbulent Mixing in the Outer Solar Nebula
N. J. Turner, K. Willacy, G. Bryden +1
The effects of turbulence on the mixing of gases and dust in the outer Solar nebula are examined using 3-D MHD calculations in the shearing-box approximation with vertical stratifi…
Electron Abundance in Protostellar Cores
Paolo Padoan, Karen Willacy, William Langer +1
The determination of the fractional electron abundance, Xe, in protostellar cores relies on observations of molecules, such as DCO+, H13CO+ and CO, and on chemical models to interp…
