New chondritic bodies identified in eight oxygen-bearing white dwarfs
Alexandra E. Doyle, Beth L. Klein, Patrick Dufour +8
We present observations and analyses of eight white dwarf stars that have accreted rocky material from their surrounding planetary systems. The spectra of these helium-atmosphere w…
Unusual Abundances from Planetary System Material Polluting the White Dwarf G238-44
Ted M Johnson, Beth L. Klein, D. Koester +3
Ultraviolet and optical spectra of the hydrogen-dominated atmosphere white dwarf star G238-44 obtained with FUSE, Keck/HIRES, HST/COS, and HST/STIS reveal ten elements heavier than…
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…
Compositions of Planetary Debris around Dusty White Dwarfs
Siyi Xu, Patrick Dufour, Beth Klein +5
The photospheres of some white dwarfs are "polluted" by accretion of material from their surrounding planetary debris. White dwarfs with dust disks are often heavily polluted and h…
Shallow Ultraviolet Transits of WD 1145+017
Siyi Xu, Na'ama Hallakoun, Bruce Gary +16
WD 1145+017 is a unique white dwarf system that has a heavily polluted atmosphere, an infrared excess from a dust disk, numerous broad absorption lines from circumstellar gas, and…
A dearth of small particles in the transiting material around the white dwarf WD 1145+017
S. Xu, S. Rappaport, R. van Lieshout +35
White dwarf WD 1145+017 is orbited by several clouds of dust, possibly emanating from actively disintegrating bodies. These dust clouds reveal themselves through deep, broad, and e…
