Empirical temperature calibrations for early-type stars.
Abstract
Three temperature calibrations of suitable photometric quantities have been derived for O and B stars. A sample of 120 stars with reliable T(eff.) determinations has been used for establishing each calibration. The different calibrations have been critically discussed and compared. Temperature determinations for 1009 program stars have been obtained with an accuracy of the order of 10 percent.
