Efficient radiative transfer techniques in hydrodynamic simulations
Anthony Mercer, Dimitris Stamatellos, Alex Dunhill
Radiative transfer is an important component of hydrodynamic simulations as it determines the thermal properties of a physical system. It is especially important in cases where hea…
Accretion kinematics through the warped transition disk in HD142527 from resolved CO(6-5) observations
Simon Casassus, Sebastian Marino, Sebastian Perez +10
The finding of residual gas in the large central cavity of the HD142527 disk motivates questions on the origin of its non-Keplerian kinematics, and possible connections with planet…
Planet formation signposts: observability of circumplanetary disks via gas kinematics
Sebastian Perez, Alex Dunhill, Simon Casassus +5
The identification of on-going planet formation requires the finest angular resolutions and deepest sensitivities in observations inspired by state-of-the-art numerical simulations…
1D accretion discs around eccentric planets: observable near-infrared variability
Alex Dunhill
I present the results of 1D models of circumplanetary discs around planets on eccentric orbits. I use a classical viscous heating model to calculate emission fluxes at the waveleng…
Precession and accretion in circumbinary discs: The case of HD 104237
Alex Dunhill, Jorge Cuadra, Catherine Dougados
We present the results of smoothed particle hydrodynamics (SPH) simulations of the disc around the young, eccentric stellar binary HD 104237. We find that the binary clears out a l…
Misaligned accretion on to supermassive black hole binaries
Alex Dunhill, Richard Alexander, Chris Nixon +1
We present the results of high-resolution numerical simulations of gas clouds falling onto binary supermassive black holes to form circumbinary accretion discs, with both prograde…
The curiously circular orbit of Kepler-16b
Alex Dunhill, Richard Alexander
The recent discovery of a number of circumbinary planets lends a new tool to astrophysicists seeking to understand how and where planet formation takes place. Of the increasingly n…
A limit on eccentricity growth from global 3-D simulations of disc-planet interactions
Alex Dunhill, Richard Alexander, Phil Armitage
We present high resolution 3-D simulations of the planet-disc interaction using smoothed particle hydrodynamics, to investigate the possibility of driving eccentricity growth by th…
