The White Dwarf Luminosity Function: The Shape of Things to Come
T. von Hippel, M. Kilic, J. Munn +10
We describe a new survey for cool white dwarfs that supplements Sloan Digital Sky Survey photometry with USNO proper motions and follow-up spectroscopy. To date we have discovered…
Cataclysmic Variables from SDSS III. The Third Year
Paula Szkody, Arne Henden, Oliver Fraser +17
This paper continues the series that identifies new cataclysmic variables found in the Sloan Digital Sky Survey. We present 36 cataclysmic variables and one possible symbiotic star…
Parallaxes of Brown Dwarfs at USNO
H. C. Harris, C. C. Dahn, F. J. Vrba +10
Trigonometric parallaxes have been measured by Dahn et al. (2002) for 28 cool dwarfs and brown dwarfs, including 17 L dwarfs and three T dwarfs. Broadband CCD and near-IR photometr…
RR Lyrae Stars and Anomalous Cepheids in the Draco Dwarf Spheroidal Galaxy
K. Kinemuchi, H. A. Smith, A. LaCluyze +4
We present new results on RR Lyrae stars and anomalous Cepheids in the Draco dwarf spheroidal galaxy. We have increased the number of double-mode RR Lyrae stars and found three new…
