A Gemini Snapshot Survey for Double Degenerates
Mukremin Kilic, Warren R. Brown, A. Gianninas +3
We present the results from a Gemini snapshot radial-velocity survey of 44 low-mass white dwarf candidates selected from the Sloan Digital Sky Survey spectroscopy. To find sub-hour…
Discovery of Three Pulsating, Mixed-atmosphere, Extremely Low-mass White Dwarf Precursors
A. Gianninas, Brandon Curd, G. Fontaine +2
We report the discovery of pulsations in three mixed-atmosphere, extremely low-mass white dwarf (ELM WD, M 0.3 M) precursors. Following the recent discoveries…
A Dark Spot on a Massive White Dwarf
Mukremin Kilic, Alexandros Gianninas, Keaton J. Bell +7
We present the serendipitous discovery of eclipse-like events around the massive white dwarf SDSS J152934.98+292801.9 (hereafter J1529+2928). We selected J1529+2928 for time-series…
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…
