Scientific paper

Effective temperatures are inferred for 28 Bp stars with the Blackwell-Shallis method. They are compared to photometric estimations, which are made with Δm2100, (B-V)J, (B2-G), (R-I)c, and (J-K). It is shown that (B2-G) and (R-I)c are the most interesting temperature estimators for peculiar stars. A new calibration of (B2-G)0 is then provided for Si and He weak stars. Linear radii of Bp stars are found to be similar to those of main sequence late B-type stars.
