Other WWW sites of interest to TASS members
At the bottom is
a list of other WWW sites with the acronym TASS,
all of which are completely unrelated to The Amateur Sky Survey.
- The Cincinnati
TASS site home page, maintained by Mike Gutzwiller.
- The Dayton TASS
site home page, maintained by Glenn Gombert. It includes
informative notes such as
Hints To Setting Up A TASS Mark III Camera.
- TASS at Johns Hopkins
- Chris Albertson's
TASS Software site
- Peter Mount's Scheduler page
Andrew Bennett's TASS page includes some data analysis
of Mark IV frames.
- Martin Nicholson has gathered information on variable star candidates
have been found in TASS observations. His compilations are at:
Bush's "Blink Compare" page
- John Phillip's
page of suspected variables in 'texncat'
- Peter McCullough,
at University of Illinois Urbana-Champaign,
is very active in using TASS-like arrangments of camera lenses and CCDs.
Here are several of his projects:
- The All-Sky
Astronomical Survey plans to map bright stars over
large areas of the sky
using a CCD detector and telephone camera lens. It has already
measured over 30,000 stars and found
The Northern Sky Variability Survey
is based on
ROTSE survey .
The link above takes you to a database which you may query.
- The ATOMIC project
at Los Alamos, which uses CCD chips behind 50-mm camera lenses
to monitor sky conditions and space junk.
an international group devoted to the study of variable stars.
The Virtual Observatory Network
collects data on variable stars.
The MISAO (Multitudinous Image-based Sky survey by Accumulative
The project plans to use astronomical images from many different
sources to build up a catalog of stellar positions and brightnesses.
The site includes source code to measure stellar parameters
and calibrate them automatically.
The STARE project uses precise time-series
photometry to search for extrasolar giant planets transiting their
parent stars. Their system is very similar to the TASS Mark IV.
Variable Star Light Curves for Far Southern Stars
by Vello Tabur shows light curves for over 1,000 variable stars,
measured with a 100mm telephoto lens and CCD camera.
Vello Tabur has also found
a number of new variable stars with wide-field camera.
Sky and Telescope's Alert Service contains messages with
information on new sources and and time-critical observations.
The DIRECT Project, which aims to measure the properties
of many variable stars in local galaxies M31 and M33 in order
to determine their distances.
- The Center for
Backyard Astrophysics, The CBA is a group of amateur and
professional astronomers (mostly amateur)
collaborating to study the light curves of variable stars.
- The Spanish Variable
Star Observers' Association (AVE) has both English and
Spanish WWW pages at their site. You can find free software
for analyzing variable star data there.
The Eclipsing Binary Stars page
is run by Dan Bruton, and contains information about binary stars,
links to data, and software for analyzing them.
- Doug Welch studies pulsating variables, especially Cepheids.
He has created a couple of pages which demonstrate the behavior
of these variables:
The Nightfall program is software for Linux which analyzes
binary star light curves to build models of the system.
- AstroWeb's list of Astronomical Survey Projects
Astroweb's list of astronomy software servers
- The American Association of Variable
Star Observers: lots of information on a group with decades
of visual measurements of variable stars. Records of stars in three
constellations are available on-line as of May 27, 1997.
- The British Astronomical
Association Variable Star Section: database of current and
historical measurements of variable stars by the BAAVSS.
Tools For Variable Stars: a page of software for
the analysis of variable star light curves.
Data reduction by the MOA project. MOA stands for
"Microlensing Observations in AstroPhysics."
Information Bulletin on Variable Stars
A bulletin of IAU commissions 27 and 42, full of up-to-the-minute
news and papers on variable stars.
Check for any known asteroid at a particular location at a
particular time, thanks to the Minor Planet Center at
the Smithsonian Astrophysical Observatory.
- Two services offered by Flagstaff Observatory:
- Roy Tucker is using a CCD on the back of his Celestron C14 to look
for Near-Earth Objects; he has found a few already, using a drift-scan
technique very similar to ours.
Check out the
Goodrick-Pigott Observatory to learn more about Roy's work.
