Evolution from protoplanetary to debris discs: The transition disc around HD 166191
G. M. Kennedy, S. J. Murphy, C. M. Lisse +12
HD 166191 has been identified by several studies as hosting a rare and extremely bright warm debris disc with an additional outer cool disc component. However, an alternative inter…
Up to 700k GPU cores, Kepler, and the Exascale future for simulations of star clusters around black holes
P. Berczik, R. Spurzem, L. Wang +9
We present direct astrophysical N-body simulations with up to a few million bodies using our parallel MPI/CUDA code on large GPU clusters in China, Ukraine and Germany, with differ…
Resolved Imaging of the HR 8799 Debris Disk with Herschel
Brenda C. Matthews, Grant Kennedy, Bruce Sibthorpe +5
We present Herschel far-infrared and submillimeter maps of the debris disk associated with the HR 8799 planetary system. We resolve the outer disk emission at 70, 100, 160 and 250…
Herschel Observations of Debris Discs Orbiting Planet-hosting Subgiants
Amy Bonsor, Grant M. Kennedy, Mark C. Wyatt +2
Debris discs are commonly detected orbiting main-sequence stars, yet little is known regarding their fate as the star evolves to become a giant. Recent observations of radial veloc…
Imaged sub-stellar companions: not as eccentric as they appear? The effect of an unseen inner mass on derived orbits
Tim D. Pearce, Mark C. Wyatt, Grant M. Kennedy
Increasing numbers of sub-stellar companions are now being discovered via direct imaging. Orbital elements for some of these objects have been derived using star--companion astrome…
The bright end of the exo-Zodi luminosity function: Disk evolution and implications for exo-Earth detectability
Grant M. Kennedy, Mark C. Wyatt
We present the first characterisation of the 12um warm dust ("exo-Zodi") luminosity function around Sun-like stars, focussing on the dustiest systems that can be identified by WISE…
Spatially Resolved Images of Dust Belt(s) Around the Planet-hosting Subgiant Kappa CrB
Amy Bonsor, Grant M. Kennedy, Justin R. Crepp +4
We present Herschel spatially resolved images of the debris disc orbiting the subgiant Kappa CrB. Not only are these the first resolved images of a debris disc orbiting a subgiant,…
