The True Incidence of Magnetism Among Field White Dwarfs

  title={The True Incidence of Magnetism Among Field White Dwarfs},
  author={James William Liebert and Pierre Bergeron and Jay B. Holberg},
  journal={The Astronomical Journal},
We study the incidence of magnetism in white dwarfs from three large and well-observed samples of hot, cool, and nearby white dwarfs in order to test whether the fraction of magnetic degenerates is biased and whether it varies with effective temperature, cooling age, or distance. The magnetic fraction is considerably higher for the cool sample of Bergeron, Ruiz, & Leggett and the Holberg, Oswalt, & Sion sample of local white dwarfs than it is for the generally hotter white dwarfs of the Palomar… Expand

The incidence of magnetic fields in cool DZ white dwarfs
Little is known about the incidence of magnetic fields among the coolest white dwarfs. Their spectra usually do not exhibit any absorption lines as the bound-bound opacities of hydrogen and heliumExpand
The origin of the magnetic fields in white dwarfs
Magnetic white dwarfs with fields in excess of ∼10 6 G (the high field magnetic white dwarfs; HFMWDs) constitute about ∼10 per cent of all white dwarfs and show a mass distribution with a mean massExpand
Magnetic White Dwarfs
In this paper we review the current status of research on the observational and theoretical characteristics of isolated and binary magnetic white dwarfs (MWDs).Magnetic fields of isolated MWDs areExpand
New insight into the magnetism of degenerate stars from the analysis of a volume-limited sample of white dwarfs
Many stars evolve into magnetic white dwarfs (MWDs), and observations may help to understand when the magnetic field appears at the stellar surface, if and how it evolves during the cooling phase,Expand
Suppression of cooling by strong magnetic fields in white dwarf stars
It is found that strong fields are sufficient to suppress convection over the entire surface in cool magnetic white dwarf, which inhibits their cooling evolution relative to weakly magnetic and non-magnetic white dwarfs, making them appear younger than they truly are. Expand
A search for kilogauss magnetic fields in white dwarfs and hot subdwarf stars
We present new results of a survey for weak magnetic fields among DA white dwarfs, including some brighter hot subdwarf stars. We have detected variable circular polarization in the Hα line of theExpand
Where Are the Magnetic White Dwarfs with Detached, Nondegenerate Companions?
The Sloan Digital Sky Survey has already more than doubled the sample of white dwarfs with spectral classifications, the subset with detached M dwarf companions, and the subset of magnetic whiteExpand
Searching for the weakest detectable magnetic fields in white dwarfs. Highly-sensitive measurements from first VLT and WHT surveys
Our knowledge of the magnetism in white dwarfs is based on an observational dataset that is biased in favour of stars with very strong magnetic fields. Most of the field measurements available in theExpand
The Fraction of DA White Dwarfs with Kilo-Gauss Magnetic Fields
Context. Weak magnetic fields have been searched for on only a small number of white dwarfs. Current estimates find that about 10% of all white dwarfs have fields in excess of 1 MG; according toExpand
Measuring the rotational periods of isolated magnetic white dwarfs
We present time-series photometry of 30 isolated magnetic white dwarfs, surveyed with the Jacobus Kapteyn Telescope between 2002 August and 2003 May. We find that 9 were untestable due to varyingExpand
