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…
Infrared Variability due to Magnetic Pressure Driven Jets, Dust Ejection and Quasi-Puffed-Up Inner Rims
Kurt Liffman, Geoffrey Bryan, Mark Hutchison +1
The interaction between a YSO stellar magnetic field and its protostellar disc can result in stellar accretional flows and outflows from the inner disc rim. Gas flows with a veloci…
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…
MULTIGRAIN: Simulating mixtures of multiple dust grains and gas with SPH
Daniel J. Price, Mark Hutchison, Guillaume Laibe
We present MULTIGRAIN, an algorithm for simulating multiple phases of small dust grains embedded in a gas, building on our earlier work in simulating two-phase mixtures of gas and…
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…
