Scientific paper

High quality spectra of the triple star theta1 Ori C in the Orion Trapezium show that one more star in this system is a spectral binary. Its components are young main-sequence A-stars with masses of 1.3 and 1.4 solar mass. Radial velocities of stellar lines indicate that this binary runs away from the system in the direction to an observer with a large negative velocity. For the primary star (C3p) and the secondary (C3s) a list of lines, wavelength and equivalent width are given.
