Classification and parameterisation of a large Gaia sample of white dwarfs using XP spectra
O. Vincent, M. A. Barstow, S. Jordan +3
The latest Gaia data release in July 2022, DR3, added a number of important data products to those available in earlier releases, including radial velocity data, information on ste…
Measurement of stellar and substellar winds using white dwarf hosts
N. Walters, J. Farihi, P. Dufour +2
White dwarfs stars are known to be polluted by their active planetary systems, but little attention has been paid to the accretion of wind from low-mass companions. The capture of…
Disk or Companion: Characterizing Excess Infrared Flux in Seven White Dwarf Systems with Near-Infrared Spectroscopy
Dylan Owens, Siyi Xu, Elena Manjavacas +7
Excess infrared flux from white dwarf stars is likely to arise from a dusty debris disk or a cool companion. In this work, we present near-infrared spectroscopic observations with…
New chondritic bodies identified in eight oxygen-bearing white dwarfs
Alexandra E. Doyle, Beth L. Klein, Patrick Dufour +8
We present observations and analyses of eight white dwarf stars that have accreted rocky material from their surrounding planetary systems. The spectra of these helium-atmosphere w…
Spectrophotometric analysis of magnetic white dwarf II: Helium-rich compositions
François Hardy, Patrick Dufour, Stefan Jordan
We present an analysis of all single white dwarf stars known to exhibit spectroscopic signatures of neutral helium line splitting due to the presence of a strong magnetic field. Us…
Spectrophotometric analysis of magnetic white dwarf I: Hydrogen-rich compositions
François Hardy, Patrick Dufour, Stefan Jordan
We present an homogeneous analysis of all DA stars labeled as magnetic in the Montreal White Dwarf Database (MWDD). Our sample is restricted to almost all known magnetic white dwar…
