A Detailed Model Atmosphere Analysis of Cool White Dwarfs in DESI DR1
Mukremin Kilic, Pierre Bergeron, Simon Blouin +9
We present a detailed model atmosphere analysis of cool white dwarfs in the Dark Energy Spectroscopic Instrument Data Release 1 (DESI DR1). Our sample includes 25,642 unique target…
A Detailed Model Atmosphere Analysis of Hot White Dwarfs in DESI DR1
Mukremin Kilic, Pierre Bergeron, Adam Moss +6
We present a detailed model atmosphere analysis of hot white dwarfs in the Dark Energy Spectroscopic Instrument (DESI) Data Release 1. Our sample includes 19,321 unique targets wit…
White Dwarf Merger Remnants with Cooling Delays on the Q Branch Lack Strong Magnetism
Lou Baya Ould Rouis, J. J. Hermes, Joseph A. Guidry +8
A population of anomalous ultra-massive white dwarfs discovered with Gaia, often referred to as the Q branch, show high (multi-Gyr) cooling delays produced by exotic physical mecha…
Comparison of Ne-22 core and shell distilled WD detonations in AREPO
Uri Pierre Burmester, Lilia Ferrario, Ivo R. Seitenzahl +1
We present three-dimensional hydrodynamical simulations of detonations in white dwarfs that have undergone distillation during crystall…
JWST imaging of omega Centauri: II. Evidence for a split white dwarf cooling sequence in the near-infrared
M. Scalco, M. Salaris, L. R. Bedin +11
We present a detailed analysis of the white dwarf cooling sequence (WD CS) in omega Centauri based on combined Hubble Space Telescope (HST) and JWST observations. Our analysis conf…
The Fraction of Distilled White Dwarfs with Long-Lived Habitable Zones
Manuel Barrientos, Mukremin Kilic, Simon Blouin +3
After carbon and oxygen, Ne is the most abundant element in white dwarf interiors. As C/O white dwarfs (WDs) crystallize, they are predicted to go through a distillation pro…
White dwarf fundamentals
Simon Blouin
This chapter provides an in-depth overview of white dwarfs, the evolutionary terminus of the vast majority of stars. It discusses their discovery, their nature as degenerate object…
Ne22 distillation and the cooling sequence of the old metal-rich open cluster NGC 6791
Maurizio Salaris, Simon Blouin, Santi Cassisi +1
Recent Monte Carlo plasma simulations to study in crystallizing carbon-oxygen (CO) white dwarfs (WDs) the phase separation of Ne22 (the most abundant metal after carbon and oxygen)…
