Dust Processing in Protoplanetary Discs From Infall to Dispersal: the Origin of Solar System Isotopic Heterogeneities
Mark A. Hutchison, Maria Schönbächler, Lucio Mayer +1
The nucleosynthetic heterogeneity between different asteroids and planets is well established. These isotopic variations manifest themselves at the part per millions level or large…
Presolar grain dynamics: creating nucleosynthetic variations through a combination of drag and viscous evolution
Mark A. Hutchison, Jean-David Bodénan, Lucio Mayer +1
Meteoritic studies of solar system objects show evidence of nucleosynthetic heterogeneities that are inherited from small presolar grains (< 10 m) formed in stellar environments…
Dust delivery and entrainment in photoevaporative winds
Mark A. Hutchison, Cathie J. Clarke
We model the gas and dust dynamics in a turbulent protoplanetary disc undergoing extreme-UV photoevaporation in order to better characterise the dust properties in thermal winds (e…
Gas and multi-species dust dynamics in viscous protoplanetary discs: the importance of the dust back-reaction
Giovanni Dipierro, Guillaume Laibe, Richard Alexander +1
We study the dynamics of a viscous protoplanetary disc hosting a population of dust grains with a range of sizes. We compute steady-state solutions, and show that the radial motion…
Enforcing dust mass conservation in 3D simulations of tightly-coupled grains with the Phantom SPH code
Giulia Ballabio, Giovanni Dipierro, Benedetta Veronesi +4
We describe a new implementation of the one-fluid method in the SPH code Phantom to simulate the dynamics of dust grains in gas protoplanetary discs. We revise and extend previousl…
Grand challenges in protoplanetary disc modelling
Thomas J. Haworth, John D. Ilee, Duncan H. Forgan +18
The Protoplanetary Discussions conference --- held in Edinburgh, UK, from 7th --11th March 2016 --- included several open sessions led by participants. This paper reports on the di…
