Scientific paper

A Fabry-Perot spectrometer with an FOV of about 2 deg and pneumatic scanning in wavelength was used to search for high-galactic-latitude B stars with relatively large E(B-V). Hydrogen emission intensity measurements in the H-beta line show H II regions around the stars 103 Tau, 105 Tau, FR CMa, and Phi Per. The measured total flux in H-beta is used to determine the excitation parameter U(Sp) and the total number of Lyman continuum quanta for these stars. The measured parameters of U(Sp) are, respectively, 3.3, 2.5, 3.0, and 1.1 times greater than the theoretical ones determined by Panagia (1973). No hydrogen emission was found around Theta Cyg with small E(B-V); its emission measure parameter does not exceed 2.8 pc/cm exp 6.
