Microvariability and Oscillations of Stars
MOST is Canada's first space science microsatellite and its first
optical space telescope project, aiming for launch in late 2001.
MOST is designed to measure (as its acronym implies) Microvariability
& Oscillations of STars in broadband light with a precision
of a few micromagnitudes over timescales from minutes to days.
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
also be capable of confirming the presence of giant extrasolar
planets identified in Doppler surveys.

The MSX observatory is a Ballistic Missile Defense Organization project
which offers major benefits for both the defense and civilian

orbit. The spacecraft featured an advanced multispectral image capability to
gather data on test targets and space background phenomena.

by employing a solid hydrogen cryostat. The IR instruments span
the range 4.2 - 26 microns. The focal plane array
consists of five bands and the radiometer beam-size is more
than 25 times smaller than IRAS. As a result, much
greater spatial resolution than anything currently available has been obtained.

Molonglo Observatory Synthesis Telescope
The MOST consists of two cylindrical paraboloids, 778m x 12m,
separated by 15m and aligned East-West. A line feed system
of 7744 circular dipoles collects the signal and feeds 176
preamplifiers and 88 IF amplifiers. The telescope is steered by
mechanical rotation of the cylindrical paraboloids about their long axis,
and by phasing the feed elements along the arms. The
resulting `alt-alt' system can follow a field for +/- 6
hours (necessary for a complete synthesis with an East-West array)
only if the field is south of declination -30 degrees.
For fields near this limit the signal-to-noise ratio is considerably
lower for the first and last hour or so due
to the lower gain of the system at large `meridian

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.

In 1986, astronomers from the University of Texas established a

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.
