Index to Sources of Astronomical Data

Abstract

This page describes a selection of on-line sources of astronomical data. Preference is given to concise formats, and professional rather than hobby sites.

Bright Stars

(http://heasarc.gsfc.nasa.gov/W3Browse/all/bsc5p.html)

• Alternative name for stars in the Bright Star Catalogue (usually the Flamsteed and/or Bayer designation
• Galactic longitude and latitude

• Right Ascension and Declination
• Durchmeusterung catalog ID.
• Fifth Fundamental Catalogue (FK5) designation
• Henry Draper Catalogue number
• Harvard Revised BS Catalogue number
• Infrared source flag
• Number of components (if a multiple system)
• Identification of the components
• Magnitude difference between two components of a double, or between the two brightest components of a multiple system
• Separation of two components of a double, or between the two brightest components of a multiple system
• HR prefix (Note that stars in this catalogue are also sometimes referred to using the prefix 'BS'.)
• Parallax
• Heliocentric radial velocity in km/s
• Projected rotational velocity (v sin i)
• Smithsonian Astrophysical Observatory (SAO) designation
• Spectral type
• General Catalogue of Variable Stars (GCVS) designation
• Photographic magnitude

• the star designations in Hipparcos catalogue were added, as well as the positions expressed in the International Celestial Reference System (ICRS)
• the parallax and proper motion data were replaced by the Hipparcos values for almost all the bright stars
• the distances (expressed in light-years) were computed
• ecliptic coordinates were added to astrometric data
• UBVRI photometry was taken from Lanz (1986); for that reason, three stars (HR 3229, HR 4392 and HR 6161) are fainter than 5 mag. Moreover, the blanks due to unknown indices were filled with the value 99.99 (or 99.999 for the uvbyHbeta photometry).
• the greek letter "delta" that appears in some spectral types is now written in latin letters instead of the code "<04>".
• the luminosity classes are coded as integer numbers in an additional column.
• the number of components of visual double stars is given.

Single Stars - Specific Types

Cepheid

Wolf-Rayet

van der Hucht 2001: The VIIth catalogue of galactic Population I Wolf Rayet stars provides improved coordinates, spectral types and bv photometry of known WR stars and adds 71 new WR stars to the previous WR catalogue. This census of galactic WR stars reaches 227 stars, comprising 127 WN stars, 87 WC stars, 10 WN/WC stars and 3 WO stars. This includes 15 WNL and 11 WCL stars within 30 pc of the Galactic Center.
