Lithium pollution of a white dwarf records the accretion of an extrasolar planetesimal
Benjamin C. Kaiser, J. Christopher Clemens, Simon Blouin +4
Tidal disruption and subsequent accretion of planetesimals by white dwarfs can reveal the elemental abundances of rocky bodies in exoplanetary systems. Those abundances provide inf…
A Giant Planet Candidate Transiting a White Dwarf
Andrew Vanderburg, Saul A. Rappaport, Siyi Xu +61
Astronomers have discovered thousands of planets outside the solar system, most of which orbit stars that will eventually evolve into red giants and then into white dwarfs. During…
Toward Precision Cosmochronology: A New C/O Phase Diagram for White Dwarfs
Simon Blouin, Jérôme Daligault, Didier Saumon +2
The continuous cooling of a white dwarf is punctuated by events that affect its cooling rate. Probably the most significant of those is the crystallization of its core, a phase tra…
New Conductive Opacities for White Dwarf Envelopes
Simon Blouin, Nathaniel R. Shaffer, Didier Saumon +1
Thanks to their continuous cooling and relative simplicity, white dwarf stars are routinely used to measure the ages of stellar populations. The usefulness of white dwarfs as cosmo…
Atmospheric Temperature Inversions and He I 5876 Core Profile Structure in White Dwarfs
Beth Klein, Simon Blouin, Diego Romani +7
We report distinctive core profiles in the strongest optical helium line, He I 5876, from high-resolution high-sensitivity observations of spectral type DB white dwarfs. By analyzi…
Magnesium abundances in cool metal-polluted white dwarfs
Simon Blouin
The accretion of rocky material is responsible for the presence of heavy elements in the atmospheres of a large fraction of white dwarf stars. Those objects represent a unique oppo…
The 100 pc White Dwarf Sample in the SDSS Footprint
Mukremin Kilic, P. Bergeron, Alekzander Kosakowski +3
We present follow-up spectroscopy of 711 white dwarfs within 100 pc, and present a detailed model atmosphere analysis of the 100 pc white dwarf sample in the SDSS footprint. Our sp…
First discovery of an ultra-cool white dwarf benchmark in common proper motion with an M dwarf
M. C. Lam, N. C. Hambly, N. Lodieu +5
Ultra-cool white dwarfs are among the oldest stellar remnants in the Universe. Their efficient gravitational settling and low effective temperatures are responsible for the smooth…
