All stars in forgotten fields1/13/2023 ![]() Most of the additions are designations from catalogs mostly now forgotten (e.g., Lalande, Groombridge, and Gould ) except for certain nearby stars which are still best known by these designations. I have taken these names primarily from the Hipparcos project's web site, which lists representative names for the 150 brightest stars and many of the 150 closest stars. ProperName: A common name for the star, such as "Barnard's Star" or "Sirius".Stars present only in the Gliese Catalog, which uses 1950.0 coordinates, have had these coordinates precessed to 2000. RA, Dec: The star's right ascension and declination, for epoch 2000.0.Thus Alpha Andromedae has the field value "21Alp And", and Kappa 1 Sculptoris (no Flamsteed number) has "Kap1Scl". The Flamsteed number, if present, is given first then a three-letter abbreviation for the Bayer Greek letter the Bayer superscript number, if present and finally, the three-letter constellation abbreviation. This is a combination of the two designations. Gliese: The star's ID in the third edition of the Gliese Catalog of Nearby Stars.ĭesignation, from the Fifth Edition of the Yale Bright Star Catalog.HR: The star's ID in the Harvard Revised catalog, which is the same as its number in the Yale Bright Star Catalog.HD: The star's ID in the Henry Draper catalog, if known.StarID: The database primary key from a larger "master database" of stars.Also, since I used a larger set of data for this version, the StarID differs from versions 1.* For a full list of the updated column names, see the official database documentation on Github.įields labeled with "*" exist only in version 2.0 or higher. Version 3: The field content is very nearly the same as in Version 2, but the column headers are somewhat different, and a few extra fields (for variable star range and multiple star info) have been added to the end of each record. ![]() On this web site it is stored as a Zip file or a GZ file, which most popular unzippers can open. The database is a comma separated values (CSV) file that can be imported into most database and spreadsheet programs. 3.0, has no magnitude cutoff: any star in Hipparcos, Yale, or Gliese is represented. The name of the database comes from the three catalogs comprising its data: Hipparcos, Yale, and Gliese.Īll told, this database contains ALL stars that are either brighter than a certain magnitude cutoff (magnitude +7.5 to +9.0) or within 50 parsecs (about 160 light years) from the Sun. It contains many fainter stars not found in Hipparcos. The Gliese catalog is the most comprehensive catalog of nearby stars (those within 75 light years of the Sun).The Yale Bright Star Catalog contains basic data on essentially all naked-eye stars, including much information (such as the traditional Bayer Greek letters and Flamsteed numbers) missing from many other catalogs.The Hipparcos catalog is the largest collection of high-accuracy stellar positional data, particularly parallaxes, which makes it useful as a starting point for stellar distance data.Each of these catalogs contains information useful to amateur astronomers: The database is a subset of the data in three major catalogs: the Hipparcos Catalog,the Yale Bright Star Catalog (5th Edition), and the Gliese Catalog of Nearby Stars (3rd Edition). HYG v 1.1 database: Database containing all stars brighter than magnitude +9.0, or closer than 50 parsecs.(87476 stars).HYG 2.0: Older version of the full Hipparcos/Yale/Gliese database (almost 120,000 stars, 9 MB).HYG 3.0: Database containing all stars in Hipparcos, Yale Bright Star, and Gliese catalogs (almost 120,000 stars, 14 MB).DownloadsĬhoose the version of the database that best serves your needs: It also powers the charts elsewhere on this site. It is useful for background information on all sorts of data: star names, positions, brightnesses, distances, and spectrum information. The HYG database (v3.0) is a compilation of interesting (to me, anyway) stellar data from a variety of catalogs. The current version of the database is now hosted at Github as well as here.
