Near-infrared variability in dusty white dwarfs: tracing the accretion of planetary material
Laura K. Rogers, Siyi Xu, Amy Bonsor +4
The inwards scattering of planetesimals towards white dwarfs is expected to be a stochastic process with variability on human time-scales. The planetesimals tidally disrupt at the…
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…
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 new class of Super-Earths formed from high-temperature condensates: HD219134 b, 55 Cnc e, WASP-47 e
Caroline Dorn, John H. D. Harrison, Amy Bonsor +1
We hypothesise that differences in the temperatures at which the rocky material condensed out of the nebula gas can lead to differences in the composition of key rocky species (e.g…
Extrasolar comets : the origin of dust in exozodiacal disks?
Ulysse Marboeuf, Amy Bonsor, Jean-Charles Augereau
Comets have been invoked in numerous studies as a potentially important source of dust and gas around stars, but none has studied the thermo-physical evolution, out-gassing rate, a…
An Unbiased Near-infrared Interferometric Survey for Hot Exozodiacal Dust
Steve Ertel, Jean-Charles Augereau, Olivier Absil +5
Exozodiacal dust is warm or hot dust found in the inner regions of planetary systems orbiting main sequence stars, in or around their habitable zones. The dust can be the most lumi…
