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…
Host-star and exoplanet composition: Polluted white dwarf reveals depletion of moderately refractory elements in planetary material
Claudia Aguilera-Gómez, Laura K. Rogers, Amy Bonsor +6
Planets form from the same cloud of molecular gas and dust as their host stars. Confirming if planetary bodies acquire the same refractory element composition as their natal disc d…
Semi-supervised Spectral Classification of DESI White Dwarfs by Dimensionality Reduction
Xander Byrne, Amy Bonsor, Laura K. Rogers +1
As a new generation of large-sky spectroscopic surveys comes online, the enormous data volume poses unprecedented challenges in classifying spectra. Modern unsupervised techniques…
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…
