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…
Fragmentation with Discontinuous Galerkin schemes: Non-linear fragmentation
Maxime Lombart, Mark Hutchison, Yueh-Ning Lee
Small grains play an essential role in astrophysical processes such as chemistry, radiative transfer, gas/dust dynamics. The population of small grains is mainly maintained by the…
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…
MULTIGRAIN: A smoothed particle hydrodynamics algorithm for multiple small dust grains and gas
Mark A. Hutchison, Daniel J. Price, Guillaume Laibe
We present a new algorithm, MULTIGRAIN, for modelling the dynamics of an entire population of small dust grains immersed in gas, typical of conditions that are found in molecular c…
Phantom: A smoothed particle hydrodynamics and magnetohydrodynamics code for astrophysics
Daniel J. Price, James Wurster, Terrence S. Tricco +24
We present Phantom, a fast, parallel, modular and low-memory smoothed particle hydrodynamics and magnetohydrodynamics code developed over the last decade for astrophysical applicat…
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…
On the maximum grain size entrained by photoevaporative winds
Mark A. Hutchison, Guillaume Laibe, Sarah T. Maddison
We model the behaviour of dust grains entrained by photoevaporation-driven winds from protoplanetary discs assuming a non-rotating, plane-parallel disc. We obtain an analytic expre…
A Plane-Parallel Wind Solution For Testing Numerical Simulations of Photoevaporation
Mark A. Hutchison, Guillaume Laibe
Here we derive a Parker-wind like solution for a stratified, plane-parallel atmosphere undergoing photoionisation. The difference compared to the standard Parker solar wind is that…
On dust entrainment in photoevaporative winds
Mark A. Hutchison, Daniel J. Price, Guillaume Laibe +1
We investigate dust entrainment by photoevaporative winds in protoplanetary discs using dusty smoothed particle hydrodrodynamics (SPH). We use unequal-mass particles to resolve mor…
A Reaction Plane Detector for PHENIX at RHIC
E. Richardson, Y. Akiba, N. Anderson +25
A plastic scintillator paddle detector with embedded fiber light guides and photomultiplier tube readout, referred to as the Reaction Plane Detector (RXNP), was designed and instal…
