Resumen:

We present the results of a spectroscopic analysis and spectral energy distribution (SED) modeling for a young B-type star IRAS 22150+6109. The optical multicolor photometric data were obtained at the Tien-Shan Astronomical Observatory near Almaty, Kazakhstan. Infrared photometry was taken from various sky surveys, such as IRAS, WISE, and AKARI. High-resolution optical spectra were obtained at the 3.6 m Canada-France-Hawaii Telescope (CFHT) and the 2.1 m telescope of the Observatorio Astronomico Nacional San Pedro Martir (OAN SPM). Fundamental parameters of the star are estimated under an assumption that it has a zero-age main-sequence luminosity and a spectral type of B3. The best fit to the SED implies that a large disk is located very far from the star (136 AU) and extended to 850 AU.
