| Abstract: | We analyze the calibrations (the dependence of the spectral type of a star on its effective temperature) by comparing the calculated ionization structure of an H II region with that obtained from observations for the source Orion A in radio recombination H and He lines. The effective temperature of the star ?1 Ori C (the ionization source) is most likely ≈37 000 K. |
