Velocity-imaging the rapidly precessing planetary disc around the white dwarf HE 1349-2305 using Doppler tomography
Christopher J. Manser, Erik Dennihy, Boris T. Gänsicke +11
The presence of planetary material in white dwarf atmospheres, thought to be accreted from a dusty debris disc produced via the tidal disruption of a planetesimal, is common. Appro…
Collisions in a gas-rich white dwarf planetary debris disc
Andrew Swan, Scott J. Kenyon, Jay Farihi +5
WD 0145+234 is a white dwarf that is accreting metals from a circumstellar disc of planetary material. It has exhibited a substantial and sustained increase in 3-5 micron flux sinc…
Five New Post-Main-Sequence Debris Disks with Gaseous Emission
Erik Dennihy, Siyi Xu, Samuel Lai +13
Observations of debris disks, the products of the collisional evolution of rocky planetesimals, can be used to trace planetary activity across a wide range of stellar types. The mo…
Astro 2020 Science White Paper: Evolved Planetary Systems around White Dwarfs
Boris Gaensicke, Martin Barstow, Amy Bonsor +25
Practically all known planet hosts will evolve into white dwarfs, and large parts of their planetary systems will survive this transition - the same is true for the solar system be…
Dust Production and Depletion in Evolved Planetary Systems
J. Farihi, R. van Lieshout, P. W. Cauley +15
The infrared dust emission from the white dwarf GD 56 is found to rise and fall by 20% peak-to-peak over 11.2 yr, and is consistent with ongoing dust production and depletion. It i…
