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…
