igence. The high-precision multi-epoch photometry has been used to measure variability and stellar pulsations in many classes of objects. The Hipparcos and Tycho Catalogues are now routinely used to point ground-based telescopes, navigate space missions, and drive public planetaria.
Since 1997, several thousand scientific papers have been published making use of the Hipparcos and Tycho Catalogues. A detailed review of the Hipparcos scientific literature between 1997–2007 was published in 2009, and a popular account of the project in 2010. Some examples of notable results include (listed chronologically):
- unexpected stellar velocity distribution in the warped Galactic disk
- confirming the Lutz Kelker bias of parallax measurement
- refining the Oort and Galactic constants
- Galactic disk dark matter, terrestrial impact cratering and the law of large numbers
- evidence of a galaxy merger in the early formation history of the Milky Way
- close approaches of stars to the Solar System
- local kinematics of K and M giants and the concept of superclusters
- an improved reference frame for long-term Earth rotation studies
- the local stellar velocity field in the Galaxy
- Identification of two possible "siblings" of the Sun (HIP 87382 and HIP 47399), to be studied for evidence of exoplanets
One controversial result has been the derived proximity, at about 120 parsecs, of the Pleiades cluster, established both from the original catalogue as well as from the revised analysis. This has been contested by various other recent work, placing the mean cluster distance at around 130 parsecs.
