Abstract

The determination of stellar temperatures and surface gravities by means of the Stromgren uvby beta photometric system is examined in the region of main sequence stars. We used a sample of stars with independently derived temperatures and gravities. In particular, the calibrations of Moon & Dworetsky (1985), Lester et al. (1986), and Balona (1984) are discussed. We compare our results with Castelli (1991) and present new temperature calibrations for normal, Johnson, and Ap stars. The use of integrated fluxes and especially the infrared flux method for determining stellar temperatures is discussed. Surface gravities of B and A stars, derived by fitting theoretical profiles to the Balmer lines, are used to check the calibrations.
