Physics:Catalogue of spectroscopic binary orbits

From HandWiki

The catalogue of spectroscopic binary orbits (SB) is a compilation of orbital data for spectroscopic binary stars which have been produced since 1969 by Alan Henry Batten of the Dominion Astrophysics Observatory[1] and various collaborators.[2] At the 24th International Astronomical Union general assembly, in 2000, a working group was established to take responsibility for maintenance of the catalogue, and to take it from a paper based system to an online database.[3]

As of 7 August 2009, the catalogue database contained information on over 2940 binary systems, and was estimated for completion by 2015.[4]

Applications

The catalogue is used for a variety of purposes:

  • Completeness assessments and statistical analysis
  • Generation of H-R diagrams and definition of shortest period
  • Computation of period & eccentricity relationships
