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).
