Spectroscopic Monitoring of Metal Lines in Polluted White Dwarfs
Laura K. Rogers, Michael M. Shara, Amy Bonsor +12
The disruption and accretion of planetary material onto white dwarfs is expected to be inherently dynamic and stochastic, potentially driving variability in the accretion rate and…
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…
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…
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…
Infrared Excesses around Bright White Dwarfs from Gaia and unWISE. II
Samuel Lai, Erik Dennihy, Siyi Xu +7
Infrared excesses around white dwarf stars indicate the presence of various astrophysical objects of interest, including companions and debris disks. In this second paper of a seri…
A near-infrared interferometric survey of debris-disc stars. V. PIONIER search for variability
S. Ertel, D. Defrère, O. Absil +10
Context: Extended circumstellar emission has been detected within a few 100 milli-arcsec around > 10% of nearby main sequence stars using near-infrared interferometry. Follow-up ob…
