Activity in White Dwarf Debris Disks I: Spitzer Legacy Reveals Variability Incompatible with the Canonical Model
Hiba Tu Noor, Jay Farihi, Scott J. Kenyon +11
This study presents all available, multi-epoch 3.6 and 4.5 m photometry from Spitzer Space Telescope observations of white dwarf debris disks, including weekly cadence observati…
Seven white dwarfs with circumstellar gas discs II: Tracing the composition of exoplanetary building blocks
L. K. Rogers, A. Bonsor, S. Xu +8
This second paper presents an in-depth analysis of the composition of the planetary material that has been accreted onto seven white dwarfs with circumstellar dust and gas emission…
The chemistry of extra-solar materials from white dwarf planetary systems
Siyi Xu, Laura K. Rogers, Simon Blouin
White dwarf planetary systems provide a unique way to measure the bulk composition of exoplanetary material. Extrasolar asteroids/comets/moons which have survived the evolution of…
Modeling Circumstellar Gas Emission around a White Dwarf Using Cloudy
Siyi Xu, Sherry Yeh, Laura. K. Rogers +9
The chemical composition of an extrasolar planet is fundamental to its formation, evolution and habitability. In this study, we explore a new way to measure the chemical compositio…
Seven white dwarfs with circumstellar gas discs I: white dwarf parameters and accreted planetary abundances
L. K. Rogers, A. Bonsor, S. Xu +9
Observations of planetary material polluting the atmospheres of white dwarfs are an important probe of the bulk composition of exoplanetary material. Medium- and high-resolution op…
WD0141-675: A case study on how to follow-up astrometric planet candidates around white dwarfs
Laura K. Rogers, John Debes, Richard J. Anslow +22
This work combines spectroscopic and photometric data of the polluted white dwarf WD0141-675 which has a now retracted astrometric super-Jupiter candidate and investigates the most…
