A Comprehensive Study of the Magnetic White Dwarfs in DESI DR1
Adam Moss, Pierre Bergeron, Mukremin Kilic +2
As the end point of stellar evolution for most stars, white dwarfs offer powerful insight into stellar magnetism. Multiple formation channels are required to explain the observed p…
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…
Multiperiodic pulsations of the unique DAQ white dwarf J0551+4135: insights into a merger remnant
Murat Uzundag, Mukremin Kilic, Francisco C. De Gerónimo +7
2MASS J05513444+4135297 (herafter J0551+4135) is the only pulsating DAQ white dwarf known with a carbon and hydrogen atmosphere. Its unusual atmospheric composition and kinematics…
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…
An All-sky Survey of White Dwarf Merger Remnants: Far-UV is the Key
Mukremin Kilic, Pierre Bergeron, Warren R. Brown +5
The majority of merging white dwarfs leave behind a white dwarf remnant. Hot/warm DQ white dwarfs with carbon-rich atmospheres have high masses and unusual kinematics. All evidence…
Magnetic White Dwarfs in the SDSS 100 pc Sample: Further Evidence of Two Formation Channels
Adam Moss, Mukremin Kilic, Pierre Bergeron +5
We conduct a model atmosphere analysis on all magnetic white dwarfs in the SDSS 100 pc sample. We have 163 magnetic targets in this sample, 87 of which are new discoveries, making…
Asteroseismology of WD J004917.14-252556.81, the Most Massive Pulsating White Dwarf
O. Caliskan, M. Uzundag, M. Kilic +10
We present extensive follow-up time-series photometry of WD J00492525, the most massive pulsating white dwarf currently known with and $\log{\i…
Discovery of the richest pulsating ultra-massive white dwarf
Francisco C. De Geronimo, Murat Uzundag, Alberto Rebassa-Mansergas +5
The discovery of pulsations in ultra-massive white dwarfs can help to probe their interiors and unveil their core composition and crystallized mass fraction through asteroseismic t…
The Emerging Class of Double-Faced White Dwarfs
Adam Moss, Mukremin Kilic, Pierre Bergeron +2
We report our findings on a spectroscopic survey of seven unresolved DA+DB binary white dwarf candidates. We have discovered extreme spectroscopic variations in one of these candid…
The 100 pc White Dwarf Sample in the SDSS Footprint II. A New Look at the Spectral Evolution of White Dwarfs
Mukremin Kilic, Pierre Bergeron, Simon Blouin +5
We increase the spectroscopic completeness of the 100 pc white dwarf sample in the SDSS footprint with 840 additional spectra. Our spectroscopy is 86% complete for white dwarfs hot…

We present a detailed model atmosphere analysis of massive white dwarfs with and K in the Montreal White Dwarf Database 100 pc sample and…
White Dwarf Merger Remnants: The DAQ Subclass
Mukremin Kilic, Pierre Bergeron, Simon Blouin +3
Four years after the discovery of a unique DAQ white dwarf with a hydrogen-dominated and carbon-rich atmosphere, we report the discovery of four new DAQ white dwarfs, including two…
