The 40 pc sample of white dwarfs from Gaia

Mairi W. O'Brien, P. -E. Tremblay, B. L. Klein +14

We present a comprehensive overview of a volume-complete sample of white dwarfs located within 40 pc of the Sun, a significant proportion of which were detected in Gaia Data Releas…

Seven white dwarfs with circumstellar gas discs I: white dwarf parameters and accreted planetary abundances

L. K. Rogers, A. Bonsor, S. Xu +9

Observations of planetary material polluting the atmospheres of white dwarfs are an important probe of the bulk composition of exoplanetary material. Medium- and high-resolution op…

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…

Discovery of Beryllium in White Dwarfs Polluted by Planetesimal Accretion

Beth Klein, Alexandra E. Doyle, B. Zuckerman +5

The element beryllium is detected for the first time in white dwarf stars. This discovery in the spectra of two helium-atmosphere white dwarfs was made possible only because of the…

Compositions of Planetary Debris around Dusty White Dwarfs

Siyi Xu, Patrick Dufour, Beth Klein +5

The photospheres of some white dwarfs are "polluted" by accretion of material from their surrounding planetary debris. White dwarfs with dust disks are often heavily polluted and h…

The first polluted white dwarf from Gaia DR2: the cool DAZ GaiaJ1738-0826

Carl Melis, B. Zuckerman, P. Dufour +2

We present the first metal-polluted single white dwarf star identified through Gaia DR2. GaiaJ1738-0826, selected from color and absolute magnitude cuts in the Gaia DR2 data, was d…
