Simultaneous emission from dust and gas in the planetary debris orbiting a white dwarf
Laura K. Rogers, Christopher J. Manser, Amy Bonsor +11
There is increasing evidence for the presence and variability of circumstellar dust and gas around white dwarfs that are polluted with exoplanetary material, although the origin of…
White dwarf constraints on geological processes at the population level
Andrew M. Buchan, Amy Bonsor, Laura K. Rogers +3
White dwarf atmospheres are frequently polluted by material from their own planetary systems. Absorption features from Ca, Mg, Fe and other elements can provide unique insights int…
Hunting for Polluted White Dwarfs and Other Treasures with Gaia XP Spectra and Unsupervised Machine Learning
Malia L. Kao, Keith Hawkins, Laura K. Rogers +5
White dwarfs (WDs) polluted by exoplanetary material provide the unprecedented opportunity to directly observe the interiors of exoplanets. However, spectroscopic surveys are often…
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…
