ARI Database for the Apparent Places of Fundamental Stars



Apparent and intermediate places of fundamental stars are provided by this on-line database ARIAPFS. Since 2008 apparent and intermediate places are also available via the link to the German Astrophysical Virtual Observatory (VO), as well as Greenwich Apparent Sidereal Time, Greenwich Mean Sidereal Time and Earth Rotation Angle.


For a short explanation of the content of the various files go to the INTRODUCTION; an outline is given here:

  • Tables from 1998 to 1999 for 1535 FK5 stars and Sidereal Time ==> ARIAPFS QUERY FORM
  • Tables from 2000 to 2019 for 878 FK6 Part I stars + Polaris and Sidereal Time ==> ARIAPFS QUERY FORM
  • Apparent and Intermediate Places for 878 FK6 Part I stars + 3272 FK6 Part III stars ==> VO COMPLIANT INTERFACE (App. Places FK6)
  • Apparent and Intermediate Places for more than 100000 Hipparcos stars ==> VO COMPLIANT INTERFACE (App. Places HIP)
  • Apparent and Intermediate Places for more than 1.3 billion sources Gaia DR2 ==> VO COMPLIANT INTERFACE (App. Places Gaia DR2)
  • Greenwich Apparent Sidereal Time, Greenwich Mean Sid. Time, Earth Rotation Angle ==> VO COMPLIANT INTERFACE (GAST, GMST, ERA)
