Magnetically guided accretion and extremely slow rotation in a metal-enriched white dwarf
S. Bagnulo, M. A. Stroet, C. P. Folsom +3
White dwarfs that show atmospheric metal enrichment offer a direct window into the bulk composition of exoplanetary material and provide some of the most direct constraints on the…
Searching for magnetic fields in featureless white dwarfs with the DIPOL-UF polarimeter at the Nordic Optical Telescope
A. Berdyugin, J. D. Landstreet, S. Bagnulo +2
About 20% of the white dwarfs possess a magnetic field that may be detected by the splitting and/or polarization of their spectral lines. As they cool, the effective temperatures o…
Atmospheric heating and magnetism driven by Ne distillation in isolated white dwarfs
A. F. Lanza, N. Z. Rui, J. Farihi +2
The origin of atmospheric heating in the cool, magnetic white dwarf GD 356 remains unsolved nearly 40 years after its discovery. This once idiosyncratic star with $T_{\rm eff}\appr…
Metal accretion scars may be common on magnetic, polluted white dwarfs
S. Bagnulo, J. D. Landstreet, J. Farihi +3
More than 30% of white dwarfs exhibit atmospheric metals, which are understood to be from recent or ongoing accretion of circumstellar debris. In cool white dwarfs, surface motions…
The magnetic field of the chemically peculiar star V352Peg
L. Fréour, C. Neiner, J. D. Landstreet +2
We present a spectropolarimetric analysis of the hot star V352Peg. We have acquired 18 spectropolarimetric observations of the star with ESPaDOnS at the CFHT between 2018 and 2019…
MOBSTER -- VI. The crucial influence of rotation on the radio magnetospheres of hot stars
M. E. Shultz, S. P. Owocki, A. ud-Doula +13
Numerous magnetic hot stars exhibit gyrosynchrotron radio emission. The source electrons were previously thought to be accelerated to relativistic velocities in the current sheet f…
