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…
Dormant black hole candidates from Gaia DR3 summary diagnostics
Johanna Müller-Horn, Hans-Walter Rix, Kareem El-Badry +4
We present a rigorous identification of candidates for dormant black holes (BHs) and neutron stars (NSs) in binaries using summary statistics from Gaia DR3, rather than full orbita…
Long-term eclipse time variations in white dwarf binaries
Amalie Yates, S. G. Parsons, A. J. Brown +15
The overwhelming majority of eclipsing white dwarf (WD) binary systems show quasi-periodic variations in eclipse timings on many year timescales. Currently, the mechanism behind th…
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…
The ZZ Ceti Instability Strip for The Most Massive White Dwarf Pulsators
Gracyn Jewett, Mukremin Kilic, Adam Moss +10
We present time-series photometry of 31 massive DA white dwarfs with within the ZZ Ceti instability strip from the Montreal White Dwarf Database 100 pc sampl…
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…
