The MIRI Excesses around Degenerates (MEAD) Survey I: A candidate cold brown dwarf in orbit around the nearby white dwarf 2MASS J09424023-4637176
Loïc Albert, Sabrina R. Poulsen, Érika Le Bourdais +17
The MIRI Excesses Around Degenerates Survey is a Cycle 2 James Webb Space Telescope (JWST) Survey program designed to image nearby white dwarfs in the mid-IR with the MIRI imaging…
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…
A hot white dwarf merger remnant revealed by an ultraviolet detection of carbon
Snehalata Sahu, Antoine Bédard, Boris T. Gänsicke +7
Atmospheric carbon has been detected in the optical spectra of six hydrogen-rich ultra-massive white dwarfs, revealing large carbon abundances (log C/H > 0.5) attributable to th…
Subtle and Spectacular: Diverse White Dwarf Debris Disks Revealed by JWST
J. Farihi, K. Y. L. Su, C. Melis +5
This letter reports 12 novel spectroscopic detections of warm circumstellar dust orbiting polluted white dwarfs using JWST MIRI. The disks span two orders of magnitude in fractiona…
