LSST: from Science Drivers to Reference Design and Anticipated Data Products
Željko Ivezić, Steven M. Kahn, J. Anthony Tyson +310
(Abridged) We describe here the most ambitious survey currently planned in the optical, the Large Synoptic Survey Telescope (LSST). A vast array of science will be enabled by a sin…
Properties of Ellipticity Correlation with Atmospheric Structure from Gemini South
S. Asztalos, W. H. de Vries, L. J Rosenberg +5
Cosmic shear holds great promise for a precision independent measurement of , the mass density of the universe relative to the critical density. The signal is expected to b…
Photometric Identification of Cool White Dwarfs
M. Kilic, D. E. Winget, Ted von Hippel +1
We investigate the use of a narrow-band DDO51 filter for photometric identification of cool white dwarfs. We report photometric observations of 30 known cool white dwarfs with temp…
Confirmation of SBS 1150+599A As An Extremely Metal-Poor Planetary Nebula
George Jacoby, John Feldmeier, Charles F. Claver +4
SBS 1150+599A is a blue stellar object at high galactic latitude discovered in the Second Byurakan Survey. New high-resolution images of SBS 1150+599A are presented, demonstrating…
DDO Photometry of M71: Carbon and Nitrogen Patterns Among Evolving Giants
M. M. Briley, G. H. Smith, C. F. Claver
We present V, B-V, and DDO C(41-42) and C(42-45) photometry for a sample of 75 red giants down to M_V = +2 in the relatively metal-rich Galactic globular cluster M71. The C(41-42)…
Understanding the Cool DA White Dwarf, G29-38
S. J. Kleinman, R. E. Nather, D. E. Winget +37
The white dwarfs are promising laboratories for the study of cosmochronology and stellar evolution. Through observations of the pulsating white dwarfs, we can measure their interna…
