A Spectro-photometric Analysis of Cool White Dwarfs in the Gaia and Pan-STARRS Footprint
Alexandre Caron, Pierre Bergeron, Simon Blouin +1
We present a spectro-photometric analysis of 2880 cool white dwarfs within 100 pc of the Sun and cooler than Teff = 10,000 K, with grizy Pan-STARRS photometry and Gaia trigonometri…
A New Method for Finding Nearby White Dwarf Exoplanets and Detecting Biosignatures
Mary Anne Limbach, Andrew Vanderburg, Kevin B. Stevenson +5
We demonstrate that the James Webb Space Telescope (JWST) can detect infrared (IR) excess from the blended light spectral energy distribution of spatially unresolved terrestrial ex…
Missing metals in DQ stars: A simple explanation
Simon Blouin
Classical DQ stars are white dwarfs whose atmospheres contain detectable traces of carbon brought up to the surface by a convective dredge-up process. Intriguingly, unlike other wh…
Current challenges in the physics of white dwarf stars
D. Saumon, S. Blouin, P. -E. Tremblay
White dwarfs are a class of stars with unique physical properties. They present many challenging problems whose solution requires the application of advanced theories of dense matt…
On the Nature of Ultracool White Dwarfs: Not so Cool Afterall
P. Bergeron, Mukremin Kilic, Simon Blouin +3
A recent analysis of the 100 pc white dwarf sample in the SDSS footprint demonstrated for the first time the existence of a well defined ultracool -- or IR-faint -- white dwarf seq…
First semi-empirical test of the white dwarf mass-radius relationship using a single white dwarf via astrometric microlensing
Peter McGill, Jay Anderson, Stefano Casertano +15
In November 2019, the nearby single, isolated DQ-type white dwarf LAWD 37 (WD 1142-645) aligned closely with a distant background source and caused an astrometric microlensing even…
