Carbon isotope fractionation in protoplanetary disks
Paul M. Woods, Karen Willacy
We investigate the gas-phase and grain-surface chemistry in the inner 30 AU of a typical protoplanetary disk using a new model which calculates the gas temperature by solving the g…
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…
The chemistry of multiply deuterated molecules in protoplanetary disks. I. The outer disk
K. Willacy
We present new models of the deuterium chemistry in protoplanetary disks, including, for the first time, multiply deuterated species. We use these models to explore whether observa…
Benzene formation in the inner regions of protostellar disks
Paul M. Woods, Karen Willacy
Benzene (c-C6H6) formation in the inner 3 AU of a protostellar disk can be efficient, resulting in high abundances of benzene in the midplane region. The formation mechanism is dif…
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…
