A cool, magnetic white dwarf accreting planetary debris
Stephane Vennes, Adela Kawka, Beth L. Klein +3
We present an analysis of spectroscopic data of the cool, highly magnetic and polluted white dwarf 2MASS J0916-4215. The atmosphere of the white dwarf is dominated by hydrogen, but…
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…
