Abstract: This paper is devoted to the study of gas-and-dust disks around young AB stars in the association Orion OB1. The observed spectral flux values of these stars in the wavelength range of 0.36–100 μm are determined. We used the results of multicolor photometric observations in the UBVRIJHK-bands, as well as data from the WISE and IRAS catalogs. It is shown that many program stars have radiation excesses in the far IR range. It is assumed that such an excess may be the result of the formation of a gas-dust disk around the program stars similar to those for Vega-type stars.
