Multi-band light curve analysis of the 40.5-minute period eclipsing double-degenerate binary SDSS J082239.54304857.19
Alekzander Kosakowski, Mukremin Kilic, Warren R. Brown
We present the Apache Point Observatory BG40 broadband and simultaneous Gemini -band and -band high-speed follow-up photometry observations and analysis of the 40.5 minute pe…
The 100 pc White Dwarf Sample in the SDSS Footprint
Mukremin Kilic, P. Bergeron, Alekzander Kosakowski +3
We present follow-up spectroscopy of 711 white dwarfs within 100 pc, and present a detailed model atmosphere analysis of the 100 pc white dwarf sample in the SDSS footprint. Our sp…
The ELM Survey South. I. An Effective Search for Extremely Low Mass White Dwarfs
Alekzander Kosakowski, Mukremin Kilic, Warren R. Brown +1
We begin the search for extremely-low mass (, ELM) white dwarfs (WDs) in the southern sky based on photometry from the VST ATLAS and SkyMapper surveys. We use a…
A 1201 s Orbital Period Detached Binary: the First Double Helium Core White Dwarf LISA Verification Binary
Warren R. Brown, Mukremin Kilic, A. Bedard +2
We report the discovery of a 1201 s orbital period binary, the third shortest-period detached binary known. SDSS J232230.20+050942.06 contains two He-core white dwarfs orbiting wit…
Two new Double-lined Spectroscopic Binary White Dwarfs
Mukremin Kilic, A. Bedard, P. Bergeron +1
We present radial velocity observations of four binary white dwarf candidates identified through their over-luminosity. We identify two new double-lined spectroscopic binary system…
The ELM Survey. VIII. 98 Double White Dwarf Binaries
Warren R. Brown, Mukremin Kilic, Alekzander Kosakowski +7
We present the final sample of 98 detached double white dwarf (WD) binaries found in the Extremely Low Mass (ELM) Survey, a spectroscopic survey targeting <0.3 Msun He-core WDs com…
