A Catalog of Spectroscopically Identified White Dwarfs

摘要: A catalog of 2249 white dwarfs which have been identified spectroscopically is presented complete through 1996 April. This compilation the fourth edition Villanova Catalog Spectroscopically Identified White Dwarfs. For each degenerate star, following data entries with references are provided: (1) a coordinate designation or WD number, in order right ascension; (2) ascension and declination for epoch 1950.0; (3) spectral type based upon new system; (4) symbol denoting binary membership; (5) list most names known to exist given star; (6) proper motion position angle; (7) broadband UBV photometry, V, B-V, U-B; (8) multichannel spectrophotometry, v(MC), g-r; (9) Stromgren narrowband y, b-y, u-b; (10) an absolute visual magnitude best available color-magnitude calibration trigonometric parallax; (11) observed radial velocity uncorrected gravitational redshift solar motion; (12) parallax mean error when available. Notes unusual peculiar stars coded Reference Key alphabetized by first author's last name presented, as well expanded table cross-referencing all number.
