Kinematic and Dynamical Properties of Solar Neighborhood White Dwarfs from SDSS DR19 and Gaia DR3
O. Caliskan, M. Kilic, S. Bilir
We present a comprehensive kinematic and dynamical analysis of 5,837 DA white dwarfs with SDSS DR19 spectroscopy and Gaia DR3 astrometry. Using complementary spatial distributions,…
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…
Gemini and Apache Point Multi-band Optical Imaging Characterization of Fragmenting Long-period Comet C/2025 K1 (ATLAS)
Carl Ingebretsen, Bryce T. Bolin, Meredith A. MacGregor +8
We present results from multi-band g, r, and i, observations of C/2025 K1 (ATLAS) taken with the Gemini North 8.1-m/GMOS imager on 2025 December 6 and December 24, and u, g, r, i,…
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…
No Period Change in Two Long-Period AM CVn Binaries
Matthew J. Green, Thomas R. Marsh, Jan van Roestel +25
Ultracompact binary systems, consisting of two compact objects in an orbit , should exhibit measurable rates of orbital period change () due t…
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…
Observing bright pulsating white dwarfs with PLATO: A new window into the late stages of stellar evolution
Murat Uzundag, Alejandro H. Corsico, Nicholas Jannsen +17
We present the scientific case for exploiting the capabilities of the PLATO mission to study bright pulsating white dwarfs across a wide spectral range, including hydrogen-deficien…
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 DBL Survey II: towards a mass-period distribution of double white dwarf binaries
James Munday, Ingrid Pelisoli, Pier-Emmanuel Tremblay +14
Double white dwarf binaries are an important remnant of binary evolution as they are possible type Ia supernova progenitors and strong sources of gravitational waves in the low-fre…
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…
3D Model Atmospheres for Extremely Low-Mass White Dwarfs
P. -E. Tremblay, A. Gianninas, M. Kilic +4
We present an extended grid of mean three-dimensional (3D) spectra for low-mass, pure-hydrogen atmosphere DA white dwarfs (WDs). We use CO5BOLD radiation-hydrodynamics 3D simulatio…
