The Hipparcos and Tycho Catalogues
The Hipparcos and Tycho Catalogues contain
a wealth of information in a user friendly format. Available in both
printed and machine readable form, these catalogues can be exploited by
both professional and amateur astronomers. This Hipparcos web site aims
to provide support material for catalogue owners and potential
users.

online access to Volume 1 of the catalogue.

Publications related to the Hipparcos
Results (Preprints and published papers). Includes links to preprint
and journal servers for up-to-date article searches
Proceedings from the Hipparcos Venice '97
symposium presenting The Hipparcos and Tycho Catalogues and first
astrophysical results of the Hipparcos astrometry mission
A collection of selected statistics
from the catalogues: astrometric accuracies, Hertzsprung-Russell
diagrams, etc.
Celestia 2000: Celestia 2000 is a CD-ROM package containing the principal parts of the
Hipparcos and Tycho Catalogues, annexes and complementary updated
ground-based data (in binary format). The accompanying software allows
users to easily access astrometric and photometric data for all stars
contained in these Catalogues/Annexes.
Sample pages illustrating some of the features of Celestia 2000.
On-line tools and Software Packages Several research tools have been developed to facilitate on-line access to
data from the Hipparcos and Tycho Catalogues. In addition some on-line
animation tools have been developed to visualise the Hipparcos and
Tycho data.

Educational Resources
The Hipparcos and Tycho Catalogues contain a wealth of information in a
user friendly format. This site contains some ideas showing how the
catalogues can be used to conduct interesting observations by
professional and amateur astronomers.
"Hipparcos pinpoints the
stars" is an on-line reproduction of a Hipparcos poster
available from ESA which illustrates some applications of the
Hipparcos data
Variable Stars:
examples of variable stars measured by Hipparcos, including
interactive java applets which illustrate the variability of the stars
Double and Multiple
Stars: some example charts showing the geometrical
and brightness configurations for a few of the double and multiple
systems measured and catalogued by Hipparcos.
High-Proper Motion Stars: check
here for some further details on high proper motion stars, an
animation facility to visualise motions anywhere on the sky, and some
observing suggestions.
The Millennium Star Atlas: the
Hipparcos and Tycho data have been used to create the Millennium Star
Atlas. Some example pages with excercises are available on this site.
Solar System Objects: 48 minor
planets (and a few other solar system objects) were included in the
Hipparcos Catalogue observations. An animation shows the
motion of these objects with time.
Visual Resources The visual resources on the Hipparcos site are primarily related to
the data. Several java applets have been developed to visualise the
Hipparcos and Tycho data. The stereo images and Hyades movie illustrate
how the extremely accurate positions, motions and stellar distances
obtained from the Hipparcos data yield an accurate reflection of the
true stellar 3-dimensional distribution in space. The poster images
illustrate some of the scientific goals of the Hipparcos mission.
The Hipparcos Venice '97 Proceedings The Hipparcos Venice '97 Symposium was held in May 1997. The symposium had three main aims: to
present the Hipparcos and Tycho Catalogues to the scientific community; to present the first astrophysical
results from the Hipparcos mission and to reflect on possibilities offered by astrometry from space in the
future.
The Millennium Star Atlas The Millennium Star Atlas is a three-volume compilation of 1548 sky
charts resulting from a substantial collaboration between Sky
Publication Corporation (represented by Roger W. Sinnott) and the
European Space Agency and the Hipparcos scientific community
(represented by Michael Perryman, Erik Hoeg, and Hans Schrijver). The
Atlas contains one million stars to visual magnitude 11 (from the
Hipparcos and Tycho Catalogues) and 10,000 nonstellar objects

includes sample pages, plus educational excercises
