Stars and Stellar Systems

The printed version of The Astronomical Almanac contains tables of positions and other useful data for bright stars, double stars, photometric standards, spectrophotometric standards, radial velocity standards, galaxies, star clusters, radio sources, X-ray sources, quasars, pulsars, and gamma ray sources. Some of these tables are made available here. An application to search the list of bright stars by position and magnitude is now available.
