The resulting eigenfrequency data will be used primarily for stellar
seismology, to probe the structure and ages of Sun-like stars,
magnetic stars, Wolf-Rayet stars and halo subdwarfs. The subdwarfs are
expected to yield age estimates which would place a meaningful
lower limit on the age of the Universe. MOST should

Optical Correctors for Liquid Mirror Telescopes
One of the often cited limitations of liquid mirror telescopes
pertains to the small region of sky which they can
observe. Because the aberrations of a parabola increase rapidly with
field angle, classical corrector designs cannot yield subarcsecond images for
angles significantly greater than one degree. To access larger fields,
innovative corrector designs must be explored.
In these pages we
discuss the Optical Design and Testing of a family of
two-mirror correctors to compensate the aberrations of a fixed parabolic
mirror observing at a large angle from the zenith.

under construction: ROTSE-I, a 4-fold camera array using telephoto lenses
to cover a 16 degree by 16 degree field of
view and ROTSE-II, a pair of 0.45 meter aperture telescopes
to cover a 2 degree by 2 degree field of

global time-series photometry campaign at ~10 observatories worldwide such that
our target objects are visible from the night side of
the planet 24 hours a day
Whole Earth Telescope
In 1986, astronomers from the University of Texas established a
world--wide network of cooperating astronomical observatories to obtain uninterrupted time--series
measurements of variable stars. The technological goal was to resolve
the multi-periodic oscillations observed in these objects into their individual
components; the scientific goal was to construct accurate theoretical models
of the target objects, constrained by their observed behavior, from
which their fundamental astrophysical parameters could be derived. This approach
has been extremely successful, and has placed the fledgling science
of stellar seismology at the forefront of stellar astrophysics.
Wide Field Infrared Explorer
This is the website for NASA's Wide Field Infrared Explorer
(WIRE). The primary purpose of WIRE was a four month
infrared survey of the universe, focusing specifically on starburst galaxies
and luminous protogalaxies.
On 29 Mar 1999, the WIRE
mission has been declared a loss.
Wilcox Solar Observatory
The Wilcox Solar Observatory began daily observations of the Sun's
global magnetic field in May 1975, with the goal of
understanding changes in the Sun and how those changes affect
the Earth; this is now called space weather. Now low-resolution
maps are also made of the Sun's magnetic field each
day, as are observations of solar surface motions. The observatory
is located in the foothills just west of the Stanford
Robotic observatory for small telescopes located in southeastern Arizona hosting
telescopes from other institutions for a fee. See our Web
site for details. Our own scientific interests are NEO's and
minor planet astrometry and photometry.
Wisconsin Ultraviolet Photo-Polarimeter Experiment
The Wisconsin Ultraviolet Photo-Polarimeter Experiment (WUPPE) was a pioneering effort
to explore polarization and photometry in the ultraviolet (UV) spectrum.
It was the first and most comprehensive effort to exploit
the unique powers of polarimetry at wavelengths not visible on
Earth. The instrument was designed and built at the University
of Wisconsin Space Astronomy Laboratory in the 1980's. WUPPE flew
on two NASA Space Shuttle missions: ASTRO-1 and ASTRO-2.
Wolfgang-Amadeus, The University of Vienna Twin Automatic Photoelectric Telescope
We operate two robotic 75-cm telescopes for photoelectric photometry at
Fairborn Observatory in the Sonoran desert near Tucson, Arizona. Not
only are the telescopes automatic, but the observatory itself is
automatic. A site-control computer monitors weather sensors, operates the observatory
roof, and provides a nightly report to the observatory staff,
who are located in Vienna, Austria.
Wyoming Infrared Observatory
X-Ray Timing Explorer
The Rossi X-ray Timing Explorer is a Goddard mission which
was launched on December 30th, 1995. RXTE is designed to
facilitate the study of time variability in the emission of
X-ray sources with moderate spectral resolution. Time scales from microseconds
to months are covered in an instantaneous spectral range from
2 to 250 keV. It is designed for a required
lifetime of two years, with a goal of five years.
The European Space Agency's X-ray Multi-Mirror satellite is the most
powerful X-ray telescope ever placed in orbit. It has an
unprecedented sensitivity and the mission will help solve many cosmic
mysteries, ranging from enigmatic black holes to the formation of
XMM-Newton Science Operations Centre
ESA s X-ray Multi Mirror mission XMM-Newtion is the second
Cornerstone in ESA's Long Term Scientific Programme. With a large
collecting area of its mirrors and the high sensitivity of
its cameras, XMM-Newton is expected to increase radically our understanding
of high-energy sources - clues to a mysterious past, and
keys to understanding the future of the Universe.
(University of Chicago)
Yerkes Observatory in Williams Bay Wisconsin hosts the 40" refractor,
a 41" reflector, a 24" Boller & Chivens reflector, a
10" educational telescope, and support facilities. The 41" telescope is
used for research including adaptive optics studies.
