J/A+AS/130/215             Effective temperatures of Ap stars    (Sokolov, 1998)

Effective temperatures of Ap stars. Sokolov N.A. <Astron. Astrophys. Suppl. Ser. 130, 215 (1998)> =1998A&AS..130..215S
ADC_Keywords: Stars, peculiar ; Effective temperatures Keywords: stars: chemically peculiar - stars: fundamental parameters Abstract: A new method of determination of the effective temperatures of Ap stars is proposed. The method is based on the fact that the slopes of the energy distribution in the Balmer continuum near the Balmer jump for "normal" main sequence stars and Ap stars with the same effective temperature are identical. The effective temperature calibration is based on a sample of main sequence stars with well known temperatures (Sokolov, 1995, Cat. J/A+AS/110/553). File Summary:
