Metal pollution of the solar white dwarf by solar system small bodies
Daohai Li, Alexander J. Mustill, Melvyn B. Davies
White dwarfs (WDs) often show metal lines in their spectra, indicating accretion of asteroidal material. Our Sun is to become a WD in several Gyr. Here, we examine how the solar WD…
Relentless and Complex Transits from a Planetesimal Debris Disk
J. Farihi, J. J. Hermes, T. R. Marsh +11
This article reports quasi-continuous transiting events towards WD 1054-226 at d=36.2 pc and V=16.0 mag, based on simultaneous, high-cadence, multi-wavelength imaging photometry us…
The entry geometry and velocity of planetary debris into the Roche sphere of a white dwarf
Dimitri Veras, Nikolaos Georgakarakos, Alexander J. Mustill +3
Our knowledge of white dwarf planetary systems predominately arises from the region within a few Solar radii of the white dwarfs, where minor planets break up, form rings and discs…
Accretion of tidally disrupted asteroids onto white dwarfs: direct accretion versus disk processing
Daohai Li, Alexander J. Mustill, Melvyn B. Davies
Atmospheric heavy elements have been observed in more than a quarter of white dwarfs (WDs) at different cooling ages, indicating ongoing accretion of asteroidal material, whilst on…
How the formation of Neptune shapes the Kuiper belt
Simona Pirani, Anders Johansen, Alexander J. Mustill
Inward migration of giant planets is predicted by hydrodynamical simulations during the gas phase of the protoplanetary disc. The phenomenon is also invoked to explain resonant and…
A transit survey to search for planets around hot subdwarfs: I. methods and performance tests on light curves from Kepler, K2, TESS, and CHEOPS
V. Van Grootel, F. J. Pozuelos, A. Thuillier +79
Context. Hot subdwarfs experienced strong mass loss on the Red Giant Branch (RGB) and are now hot and small He-burning objects. Aims. In this project we aim to perform a transit su…
