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…
Hot Degenerates in the MCT Survey. III. A Sample of White Dwarf Stars in the Southern Hemisphere
P. Bergeron, F. Wesemael, G. Fontaine +7
We present optical spectra of 144 white dwarfs detected in the Montreal-Cambridge-Tololo (MCT) colorimetric survey, including 120 DA, 12 DB, 4 DO, 1 DQ, and 7 DC stars. We also per…
Phase Separation in Ultramassive White Dwarfs
Simon Blouin, Jerome Daligault
Ultramassive white dwarfs are extreme endpoints of stellar evolution. Recent findings, such as a missing multi-Gyr cooling delay for a number of ultramassive white dwarfs and a whi…
Recurring Planetary Debris Transits and Circumstellar Gas around White Dwarf ZTF J03281219
Zachary P. Vanderbosch, Saul Rappaport, Joseph A. Guidry +14
We present follow-up photometry and spectroscopy of ZTF J03281219 strengthening its status as a white dwarf exhibiting transiting planetary debris. Using TESS and Zwicky Transie…
