We describe a high-speed time-series CCD photometer for the prime focus of the 82 inch (2.1 m) telescope at McDonald Observatory and summarize the observational results we have obtained since it was placed into regular use in 2002 February. We compare this instrument with the three-channel time-series photometers we have previously used for the asteroseismological study of pulsating white dwarf stars, which used photomultiplier tubes (PMTs) as the detectors. We find the CCD instrument is about… 
Argos: An optimized time-series photometer
We designed a prime focus CCD photometer, Argos, optimized for high speed time-series measurements of blue variables (Nather & Mukadam 2004) for the 2.1 m telescope at McDonald Observatory. Lack of
High-Speed Time-Series CCD Photometry with Agile
We have assembled a high-speed time-series CCD photometer named Agile for the 3.5 m telescope at Apache Point Observatory, based on the design of a photometer called Argos at McDonald Observatory.
Puoko-nui: a flexible high-speed photometric system
We describe a portable CCD-based instrumentation system designed to efficiently undertake high time precision fast photometry. The key components of the system are (1) an externally triggered
Thirty-Five New Pulsating Da White Dwarf Stars
We present 35 new pulsating DA (hydrogen atmosphere) white dwarf stars discovered from the Sloan Digital Sky Survey (SDSS) and the Hamburg Quasar Survey (HQS). We have acquired high-speed time series
Time series photometry of the helium atmosphere pulsating white dwarf EC 04207−4748
We present the analysis of 71 hours of high quality time-series CCD photometry of the helium atmosphere pulsating white dwarf (DBV) EC 04207-4748 obtained using the facilities at Mt John University
Finding the Instability Strip for Accreting Pulsating White Dwarfs From Hubble Space Telescope and Optical Observations
Time-resolved low resolution Hubble Space Telescope ultraviolet spectra together with ground-based optical photometry and spectra are used to constrain the temperatures and pulsation properties of
Echo mapping of Swift J1753.5-0127
We present two epochs of coordinated X-ray-optical timing observations of the black hole candidate Swift J1753.5-0127 during its 2005 outburst. The first epoch in July occurred at outburst peak. Two
Spitzer Planet Limits Around the Pulsating White Dwarf GD66
We present infrared observations in search of a planet around the white dwarf, GD66. Time-series photometry of GD66 shows a variation in the arrival time of stellar pulsations consistent with the
Spitzer planet limits around a pulsating white dwarf
We present infrared observations in search of a planet around the white dwarf GD66. Time-series photometry of GD66 shows a variation in the arrival time of stellar pulsations consistent with the
Cataclysmic variables from sloan digital sky survey - V. The fifth year (2004)
This paper identifies the cataclysmic variables that appear in spectra obtained in 2004 as part of the Sloan Digital Sky Survey. Spectra of 41 objects, including seven systems that were previously


The Whole Earth Telescope (WET) is a global network of collaborating astronomers designed to obtain very long lightcurves, uninterrupted by daylight, of variable white dwarf stars for
HST Observation of GD 358
The success of asteroseismology lies in the correct identification of the star's normal modes of oscillation. Winget et al. (1994) identified the normal modes of a helium white dwarf pulsator, GD
The white dwarf cooling sequence of the globular cluster messier 4
We present the white dwarf sequence of the globular cluster M4, based on a 123 orbit Hubble Space Telescope exposure, with a limiting magnitude of V ~ 30 and I ~ 28. The white dwarf luminosity
The amplitude differences between CCD and PMT measurements
Using model atmospheres, quantum efficiency and transmission curves, we compute expected values for amplitudes of DAV, DBV and DOV stellar models as measured through different detectors and/or filter
The pulsation index, effective temperature, and thickness of the hydrogen layer in the pulsating DA white dwarf G117-B15A
We have measured the amplitude of the 215 s pulsation of the pulsating DA white dwarf, or ZZ Ceti star, G117-B15A in six passbands with effective wavelengths from 1570 to 6730 A. We find that the
Constraining the Evolution of ZZ Ceti
We report our analysis of the stability of pulsation periods in the DAV star (pulsating hydrogen atmosphere white dwarf) ZZ Ceti, also called R548. On the basis of observations that span 31 years, we
An independent method for determining the age of the universe
An age of 9.3 + or - 2.0 Gyr is derived for the Galactic disk on the basis of comparisons between the sudden drop in the observed luminosity distribution and theoretical evolutionary white dwarf
The Search for Planets Around Pulsating White Dwarf Stars
We introduce a new technique to search for extra-solar planets with a different sensitivity from other methods, using the pulsations of white dwarf stars as intrinsic clocks. We will search for the
