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…
Alkali metals in white dwarf atmospheres as tracers of ancient planetary crusts
Mark A. Hollands, Pier-Emmanuel Tremblay, Boris T. Gänsicke +2
White dwarfs that accrete the debris of tidally disrupted asteroids provide the opportunity to measure the bulk composition of the building blocks, or fragments, of exoplanets. Thi…
White dwarf pollution by hydrated planetary remnants: Hydrogen and Metals in WD J204713.76-125908.9
Matthew J. Hoskin, Odette Toloza, Boris T. Gänsicke +9
WD J204713.76-125908.9 is a new addition to the small class of white dwarfs with helium-dominated photospheres that exhibit strong Balmer absorption lines and atmospheric metal pol…
The frequency of gaseous debris discs around white dwarfs
Christopher J. Manser, Boris T. Gänsicke, Nicola Pietro Gentile Fusillo +5
1-3 per cent of white dwarfs are orbited by planetary dusty debris detectable as infrared emission in excess above the white dwarf flux. In a rare subset of these systems, a gaseou…
Are exoplanetesimals differentiated?
Amy Bonsor, Philip J. Carter, Mark Hollands +3
Metals observed in the atmospheres of white dwarfs suggest that many have recently accreted planetary bodies. In some cases, the compositions observed suggest the accretion of mate…
Interpretation and diversity of exoplanetary material orbiting white dwarfs
Andrew Swan, Jay Farihi, Detlev Koester +5
Nine metal-polluted white dwarfs are observed with medium-resolution optical spectroscopy,where photospheric abundances are determined and interpreted through comparison against so…
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…
A planetesimal orbiting within the debris disc around a white dwarf star
Christopher J. Manser, Boris T. Gänsicke, Siegfried Eggl +29
Many white dwarf stars show signs of having accreted smaller bodies, implying that they may host planetary systems. A small number of these systems contain gaseous debris discs, vi…
280 one-opposition near-Earth asteroids recovered by the EURONEAR with the Isaac Newton Telescope
O. Vaduvescu, L. Hudin, T. Mocnik +80
One-opposition near-Earth asteroids (NEAs) are growing in number, and they must be recovered to prevent loss and mismatch risk, and to improve their orbits, as they are likely to b…
