A Collisional Origin to Earth's Non-chondritic Composition?
Amy Bonsor, Zoë M. Leinhardt, Philip J. Carter +3
Several lines of evidence indicate a non-chondritic composition for Bulk Earth. If Earth formed from the accretion of chondritic material, its non-chondritic composition, in partic…
A near-infrared interferometric survey of debris-disc stars. IV. An unbiased sample of 92 southern stars observed in H-band with VLTI/PIONIER
Steve Ertel, Olivier Absil, Denis Defrere +8
Context. Detecting and characterizing circumstellar dust is a way to study the architecture and evolution of planetary systems. Cold dust in debris disks only traces the outer regi…
Formation of planetary debris discs around white dwarfs I: Tidal disruption of an extremely eccentric asteroid
Dimitri Veras, Zoe M. Leinhardt, Amy Bonsor +1
25%-50% of all white dwarfs (WDs) host observable and dynamically active remnant planetary systems based on the presence of close-in circumstellar dust and gas and photospheric met…
ALMA and Herschel Observations of the Prototype Dusty and Polluted White Dwarf G29-38
J. Farihi, M. C. Wyatt, J. S. Greaves +3
ALMA Cycle 0 and Herschel PACS observations are reported for the prototype, nearest, and brightest example of a dusty and polluted white dwarf, G29-38. These long wavelength progra…
Planetesimal driven migration as an explanation for observations of high levels of warm, exozodiacal dust
Amy Bonsor, Sean N. Raymond, Jean-Charles Augereau +1
High levels of exozodiacal dust have been observed in the inner regions of a large fraction of main sequence stars. Given the short lifetime of the observed small dust grains, thes…
Debris from giant impacts between planetary embryos at large orbital radii
Alan P. Jackson, Mark C. Wyatt, Amy Bonsor +1
We consider the observational signatures of giant impacts between planetary embryos. While the debris released in the impact remains in a clump for only a single orbit, there is a…
