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 dust never settles: collisional production of gas and dust in evolved planetary systems
Andrew Swan, Jay Farihi, Thomas G. Wilson +1
Multi-epoch infrared photometry from Spitzer is used to monitor circumstellar discs at white dwarfs, which are consistent with disrupted minor planets whose debris is accreted and…
Emission from elliptical streams of dusty debris around white dwarfs
C. J. Nixon, J. E. Pringle, E. R. Coughlin +2
White dwarfs are routinely observed to have polluted atmospheres, and sometimes significant infrared excesses, that indicate ongoing accretion of circumstellar dust and rocky debri…
