The Origins of Lithium Enhancement in Polluted White Dwarfs
Benjamin C. Kaiser, J. Christopher Clemens, Simon Blouin +4
The bulk abundances of exoplanetesimals can be measured when they are accreted by white dwarfs. Recently, lithium from the accretion of exoplanetesimals was detected in relatively…
JWST Resolves CIA Features in White Dwarfs
Simon Blouin, Mukremin Kilic, Loic Albert +2
Infrared-faint white dwarfs are cool white dwarfs exhibiting significant infrared flux deficits, most often attributed to collision-induced absorption (CIA) from H-He in mixed…
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…
PHL 5038AB: Is the brown dwarf causing pollution of its white dwarf host star?
S. L. Casewell, J. Debes, T. J. Dupuy +9
We present new results on PHL 5038AB, a widely separated binary system composed of a white dwarf and a brown dwarf, refining the white and brown dwarf parameters and determining th…
cecilia: A Machine Learning-Based Pipeline for Measuring Metal Abundances of Helium-rich Polluted White Dwarfs
M. Badenas-Agusti, J. Viaña, A. Vanderburg +4
Over the past several decades, conventional spectral analysis techniques of polluted white dwarfs have become powerful tools to learn about the geology and chemistry of extrasolar…
