The Merger Fraction of Ultramassive White Dwarfs
Mukremin Kilic, Adam G. Moss, Alekzander Kosakowski +6
We search for merger products among the 25 most massive white dwarfs in the Montreal White Dwarf Database 100 pc sample through follow-up spectroscopy and high-cadence photometry.…
The Rapid Rotation of the Strongly Magnetic Ultramassive White Dwarf EGGR 156
K. A. Williams, J. J. Hermes, Z. P. Vanderbosch
The distribution of white dwarf rotation periods provides a means for constraining angular momentum evolution during the late stages of stellar evolution, as well as insight into t…
The Initial-Final Mass Relation for Hydrogen-Deficient White Dwarfs
Joseph W. Barnett, Kurtis A. Williams, A. Bédard +1
The initial-final mass relation (IFMR) represents the total mass lost by a star during the entirety of its evolution from the zero age main sequence to the white dwarf cooling trac…
The White Dwarfs of the Old, Solar Metallicity Open Star Cluster Messier 67: Properties and Progenitors
Paul A. Canton, Kurtis A. Williams, Mukremin Kilic +1
The old, solar metallicity open cluster Messier 67 has long been considered a lynchpin in the study and understanding of the structure and evolution of solar-type stars. The same i…
The pulsating white dwarf G117-B15A: still the most stable optical clock known
S. O. Kepler, D. E. Winget, Zachary P. Vanderbosch +14
The pulsating hydrogen atmosphere white dwarf star G 117-B15A has been observed since 1974. Its main pulsation period at 215.19738823(63) s, observed in optical light curves, varie…
Ensemble Evolutionary Studies of White Dwarfs in Open Star Clusters
Kurtis A. Williams
White dwarfs (WDs) in open star clusters are a highly useful ensemble of stars. While numerous researchers use open cluster WDs to study the initial-final mass relation, numerous o…
