| Abstract: | Empirical formulas for the temperature and surface gravitation of white dwarfs are derived using data on temperature and the
acceleration of gravity from the catalog of spectroscopically confirmed white dwarfs WD in the Sloan Digital Sky Survey Release
4 (SDSS DR4). These formulas are used to determine the temperature and acceleration of gravity for five spectroscopically
confirmed white dwarfs from the FBS survey that were not included in the WD SDSS DR4 catalog, and also for 82 WD that had
not been spectroscopically confirmed. As a result, the temperature and acceleration of gravity have been determined for 87
FBS white dwarfs that were not included in the SDSS WD catalog. |
