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…
Ensemble Properties of the White Dwarf Population of the Old, Solar Metallicity Open Star Cluster Messier 67
Kurtis A. Williams, Paul A. Canton, A. Bellini +4
White dwarfs are excellent forensic tools for studying end-of-life issues surrounding low- and intermediate-mass stars, and the old, solar-metallicity open star cluster Messier 67…
Time-series spectroscopy of two candidate double degenerates in the open cluster NGC 6633
Kurtis A. Williams, Donald Serna-Grey, Subho Chakraborty +2
Type Ia supernovae are heavily used tools in precision cosmology, yet we still are not certain what the progenitor systems are. General plausibility arguments suggest there is pote…
The ELM Survey. VI. Eleven New Double Degenerates
A. Gianninas, Mukremin Kilic, Warren R. Brown +2
We present the discovery of 11 new double degenerate systems containing extremely low-mass white dwarfs (ELM WDs). Our radial velocity observations confirm that all of the targets…
Ultracool white dwarfs and the age of the Galactic disc
A. Gianninas, B. Curd, John R. Thorstensen +5
We present parallax observations and a detailed model atmosphere analysis of 54 cool and ultracool ( < 4000 K) white dwarfs (WDs) in the solar neighbourhood. For the f…
Habitable Planets Around White Dwarfs: an Alternate Mission for the Kepler Spacecraft
Mukremin Kilic, Eric Agol, Abraham Loeb +5
A large fraction of white dwarfs (WDs) may host planets in their habitable zones. These planets may provide our best chance to detect bio-markers on a transiting exoplanet, thanks…
